Indoor kite: Air of the Wolf 3b
Utah is more prone to have gusty winds than the gentle steady breezes that make kite flying easy.
Here is an option for making a kite that can be done indoors in the gym, which makes it doable yearround in any kind of weather.
http://www.instructables.com/id/Indoor-Kite/?ALLSTEPS
Materials:
1 sheet paper, 8 1/2” x 11”
masking tape
1 drinking straw
3' crepe paper
5' kite string
Tools: scissors, hole punch, ruler, pencil
Lay the paper in front of you (portrait style), and fold in half from top to bottom (hamburger, not hot
dog). Mark a dot 1” down from the folded edge on the left side of the paper. Mark another dot 1” up
from the open bottom of the paper, along the right hand side. Use the ruler to draw a line connecting
the two dots. Fold the top layer up along that line. Turn the paper over, match the other side to the
first, and fold that side. Tape the center seam closed. Tape the straw across the widest point of the kite
in at least 5 places. On the rib, measure down from the top 2 3/4” and in 1/2” and mark a dot. Fold a
piece of tape around the rib to cover this dot, then punch a hole where the dot is. Tie your string
through the hole. Tape the crepe paper tail to the bottom of the kite, on the side where the straw is. A
kid running in the gym will be able to keep this kite aloft.
http://www.instructables.com/id/How-to-make-a-Sled-Kite/ is one of many places on the web to get
instructions for a simple sled kite. If you use white garbage bags for the sail of the kite, the boys can
color a design on their kite with permanent markers.
Robots: Bears Elective Adventure
#3 Build a robot hand:
Trace the hand, with the thumb extended as far as possible, onto cereal box cardboard. Use a hole
punch to make a hole in the end of each finger, and also in the palm of the hand. Measure a piece of
string long enough to tie a knot through the hole in the end of the finger, run down the finger through
the hole in the palm, and have enough hanging below to hold. Tie one end of the string though the
hole in the end of a finger, trimming the loose end. Do this for each finger and the thumb. Place a
piece of scotch tape across the end of a drinking straw and, holding the taped portion, cut off the rest
of the straw. (This way, you don't have any tape sticking out beyond the piece of straw to bind your
string.) Tape the piece of straw close to the end of the finger, wrapping the tape around the finger to
hold the straw securely. Thread the string through the piece of straw. Bend the finger just below the
straw to make a joint. Repeat down the length of the finger, then thread the free end of the string
through the hole in the palm. Repeat for each finger and thumb. When you pull the strings, the fingers
will close.
#4 Build a robot:
One of the challenges to do this elective is expense. The cheapest robot instructions I've found are for
a “bristlebot”, much like a Hex Bug. The instructions below give the steps to make one from a batterypowered vibrating toothbrush such as Oral B Pulsar, double-stick tape, and a 1.5 V button cell battery.
(Walmart sells a generic version of the toothbrush in a 2-pack for about $7.50)

#5 Visit a place that uses robots:
For an easy but fun visit to see a robot in action, load up your Cubs into a dirty car and take them
through an automatic carwash!
Cartesian Diver: Bear elective Super Science #4
Scientist Rene Descartes (1596-1650) is said to have invented this toy (with slightly different
materials, no doubt!)
Materials: 2 liter soda bottle, test tube (you can also use an eyedropper, as long as it will fit through
the mouth of the bottle)
Remove any labels on the bottle. Fill it right to the top with water and leave it sitting in the sink. Fill the
test tube with water, and turn it over and put it into the top of the bottle. Some of the water will pour out
as you do this, leaving an air bubble in the test tube. Put the top on the bottle and test the diver. The
tube should float initially, then when the bottle is squeezed, it should sink. If your tube just sinks, it
doesn't have enough air. If it just floats, it has too much air. Keep trying until you get the right amount.
(Since there's nothing perishable, the diver can be stored indefinitely as long as it is stored upright so
the air bubble can't escape. Or, you can save space & just store the test tube or eyedropper and make
it fresh each time.
How it works: Archimedes' principle says that if an object is lighter than the amount of water it
displaces (pushes out of the way), then it will float. When not under pressure, our test tube weighs
less than the water it displaces, so it floats. But when you squeeze the bottle, the pressure you add
forces the air molecules to pack in tighter, so they take up less room in the test tube, and more water
comes in. Less water is displaced, and now it is heavier than the weight of the water it displaces, so it
sinks. When you let go, the air molecules spread out again, pushing water out of the test tube, and it
floats again. Watch carefully, and you can see the air bubble change size.
Oil and Water Make Cupcakes: Bear elective Super Science #5, Bear Picnic Basket,
Webelos Cast Iron Chef
Oil and water don’t mix--unless you add an emulsifier. Demonstrate how they separate quickly by
mixing ½ cup oil and 1 cup water in a see-through mug or liquid measuring cup. You can add food
coloring to make it more dramatic, and discuss oil versus water solubility.
After the boys have tried unsuccessfully to get them to stay mixed, add in an egg and mix, showing
how they no longer separate. Add two additional eggs, observing how the mix changes each
time. Then add the set of wet ingredients to a ready-made cake mix (note that some mixes use ⅓ cup
oil, 1 ¼ c water, and 2 eggs--use the directions on the box, or separately add the dry ingredients from
a recipe from scratch).
One fun variation is to make microwave cupcakes with the batter in mugs (which are easy to add ice
cream to on top and eat the whole with a spoon) or paper cups (which are fun and can be peeled
away as you eat the cake). ⅓ cup of batter in a single cup takes only 20-30 seconds to cook. Have
the boys notice that it will not brown on the outside, as would be the case for cupcakes in the
oven. Discuss how microwaves heat differently, and note that the cupcakes will be more likely to burn
from the inside out.
Rainbow Kool Aid: Bear elective Super Science #6, Bear Picnic Basket, Webelos Cast
Iron Chef
The Color Layering Activity in the Bear Leaders guide gets a flavorful twist by using Kool Aid packets
to color the different layers. Place six glass or see-through plastic cups in a row. Put nothing in the first
(yet), pour 1 tablespoon of sugar into the first cup, 2 tablespoons into the second, 3 in the third, 4 in
the fourth, and 5 tablespoons of sugar in the fifth cup. Sprinkle a small amount of red Kool Aid
(strawberry or cherry) in the first cup, orange sprinkled on the sugar in the second, yellow (lemon) in
the third cup, green (lemon lime) on the fourth, blue (blue raspberry) on the fifth, and purple (grape) on
sixth cup.
Add three tablespoons of lukewarm water to each of the six cups and have the boys help stir until the
sugar dissolves in each. Put the blue cup down. Take the blue cup and slowly pour the contents on top
of the purple liquid. You can use a spoon turned upside down over the cup to diffuse the force of the
liquid so it will more likely layer instead of mix. Now carefully pour the green on top of that, then the
yellow, orange, and finally the red. (For variation you can reverse the colors used with density--red for
the 5 tablespoon sugar cup, for example, and see how or whether that changes how well you can see
the layers.)
Let the boys examine the layers without touching, shaking, or stirring it, noting how well the layers
stayed separated (or didn’t) and talk about why. The more sugar, the more dense and heavier the
solution. The less there is the lighter it is and will stay on top better.
Then pour the whole thing into a pitcher and add water to make up 2 quarts. Stir and serve. The
flavors will be mixed but many cub boys will like it better that way. If you wish, work with the boys to
adjust the flavor balance by adding some of the unused KoolAid powder either to the whole or their
individual cups.
Elephant's Toothpaste: Webelos Adventures in Science 3g
http://www.sciencebob.com/experiments/toothpaste.php
!!! Mess alert! Bottle will overflow...a lot...guaranteed!
!!! Materials alert! Hydrogen peroxide will irritate eyes & skin! Wear goggles. Don't eat it!
16-oz plastic bottle
1 Tbsp (1 packet) dry yeast
3 Tbsp warm water
½ cup 20-volume developer (a strong hydrogen peroxide liquid used in hair dyeing)
Dishwashing soap
Food coloring, if desired
Mix the yeast with the warm water in a small cup. Put the 20-volume developer in the bottle and add
about a tablespoon of the detergent and 8 drops food color (if desired), swirling to mix. Put the bottle
in a sink or tray (it will overflow a LOT) and add the yeast. Developer is strong hydrogen peroxide
(H2O2)—like water, but with two oxygen molecules instead of one, and the yeast acts as a catalyst to
detach one of the oxygen molecules. The detergent lets it act like bubble juice and trap the oxygen
gas that's given off in little foamy bubbles. The reaction produces heat as well, so the bottle becomes
warm.
Find 20-volume developer at beauty supply store. I buy the clear kind, not the cream. A 32-oz bottle
was $3.99 at Sally's Beauty Supply in Aug 2012.
Cornstarch Water, a Non-Newtonian Liquid
!!! Mess alert! Put down a drop cloth.
!!! Disposal alert! Make sure everyone understands this is NOT to be poured down the sink or it
WILL clog the sink! Throw it in the trash when you're done!
Fill a container about half full with cornstarch. Add water slowly, mixing it in, until it stops looking
crumbly. A serving fork works better than a spoon for mixing. It takes about 1 ½ cups of water for 1
pound of cornstarch. It is better to add water to your cornstarch rather than the other way around,
because (at least in my opinion) if you get it too runny it's harder to correct than if it's too
crumbly. You'll know you have it right when it oozes when you move your hand slowly through it, but
seems solid when you hit it. Try picking up a handful and letting it ooze back into the bowl through
your fingers. Try making a cornstarch-ball. You'll have to keep it moving to keep it from melting! The
fluid is a non-Newtonian fluid because of this strange behavior: add pressure to the liquid, and its
viscosity (or ability to flow) changes.
---Have each boy mix his own batch in a recycled plastic container with a lid (margarine tub, sour
cream tub, etc.) and he can take it home with him. Do stress safe disposal!
Class comment: You can also put some into a baggie for less mess. You would miss out on that
sensation of the goop melting through your fingers, but you also miss out on a lot of the mess, and it's
easy to throw away. If you do it with a large group, you might wash hands with a hose outside. Our
helpful class member is a teacher, and when lots of kids in the class next door washed their hands in
the same sink, it did clog the pipes. And you can't use a plunger, because that adds pressure!
(If some gets on a carpet, you can wait for it to dry, then vacuum up the cornstarch.)
Balloon-in-a-bottle without heat
Poke a hole on a flat part of the bottom of an empty 2-liter soda bottle with an awl or nail. It should be
unobtrusive and you should be able to plug the hole with a fingertip. Put a 12” balloon in the bottle
and stretch the mouth of the balloon over the mouth of the bottle. You can blow up the balloon inside
the bottle, as long as you don't plug the hole, and once it is blown up, you can keep it inflated by
plugging the hole with your finger. (You can do this sneakily by feeling for the jet of air as you blow up
the balloon. This allows you to locate the hole without being caught looking for it.) It will not be able to
deflate as long as you are sealing the air hole on the bottom of the bottle. (However, if the sides of the
soda bottle aren’t very rigid, it will implode, which gives the game away a bit!) Make this a trick
contest by giving one boy a prepared bottle and the other a plain bottle with no hole poked. The boy
with the no-hole bottle will not be able to inflate his balloon much because the air already in the bottle
can't escape, and he'll only be able to blow up the balloon a little before the force of his lungs isn't able
to compress the air inside the bottle any further.
Balloon-in-a-bottle with heat
Get an empty glass 12-to-16 oz bottle (shorter neck is better) and boil about a tablespoon of water in
the bottom of it in the microwave until the bottle is very hot and there are droplets of water in the neck
of the bottle. Remove with oven mitts, and poke a 12” balloon down into the bottle and stretch the
mouth of the balloon over the mouth of the bottle. Use a chopstick to help poke it down without
puncturing it. The balloon will “inflate” as it cools and stay that way even though it isn't tied off. When
you heat the water in the bottle, it fills with steam and hot air. As the air in the bottle heats up, it
expands and some of the molecules leave the bottle. When you seal the opening of the bottle with the
balloon, you prevent any more air from entering the bottle. As the air inside cools, it exerts less
pressure and takes up less space, causing the balloon membrane to be stretched toward the inside of
the bottle—the pressure in the bottle is less than the atmospheric pressure outside the bottle.
The Weight of Air: Air of the Wolf 1a
The suggested experiment is to use a yardstick as a balance, tie balloons to both sides so that they
are in balance, and then pop one balloon. It’s supposed to tip the balance. In theory, this should
work. In real life, you’re trying to measure a very small difference with a very crude instrument. I
could not get it to work reliably with my materials. The balloons I was using were easy to blow up. It
would be more likely to work with some that are tough to blow up. That’s because they compress the
air inside more than easy-to-blow-up balloons do, maximizing the difference in weight. Also, the
longer the arms of your balance, the more sensitive it is, so don’t try to use a shorter piece of wood.
Another way to demonstrate that air has weight is simply to weigh it. For this, you will need a kitchen
or postal scale that weighs grams or tenths of ounces, a basketball, a bicycle pump, and a needle for
the pump so you can use it to inflate the ball. This combines really well with “That’s how the ball
bounces!” on page 147, where you bounce a flat ball, then inflate it and bounce it again. All you have
to do is weigh it as well. A very flat ball will weigh several tenths of an ounce less than when tightly
inflated. You can also watch the weight of the ball decrease as it deflates. Weigh the inflated ball and
the needle on the scale. Then put the needle (not attached to the pump) into the ball. This allows air
to escape. You can watch the weight shown by the scale drop as the air hisses out.
Imploding Soda Can: Air of the Wolf 1b
Put a small amount of water into an otherwise empty soda can. Get a bowl of ice water and set it near
your stove. Get a pair of tongs with which you can securely pick up the soda can. Place the soda can
directly on the burner of the stove. You will hear when the water starts to boil—let it boil for about a
minute to allow a buildup of hot, steamy air in the can. Use the tongs to pick up the can and
immediately put it top down into the cold water. If your temperature difference is great enough, it
should implode the can. What happens is that when air is heated, it expands. Some of the air leaves
the soda can. This works the same as the balloon-in-a-bottle, only quicker, because the cooling is
quicker. If you don't get a good implosion, try making the can hotter or the water colder. (If it just sucks
water up into the can, you don't have enough difference in temperature.)
Class comment: You can do this with a microwave & a milk jug, too. Put a little water in the bottom of a
milk jug, microwave, then put the lid back on and let it cool.
CD Hovercraft: Air of the Wolf 1cii
You will need a balloon, a dead CD, and the mouth of a soda or water bottle (any size). Cut the mouth
of the bottle off and hot-glue it over the center hole of the CD, making sure the glue makes a complete
seal so air can't escape. Stretch the mouth of the balloon over the mouth from the water bottle. Inflate
the balloon by turning your hovercraft over and blowing up the balloon from the CD side. Pinch or twist
the neck of the balloon to keep the air in until you're ready. (Or, use the top of a sports drink and close
the spout--it can be done through the balloon.) Put the hovercraft on a hard, smooth surface, let the
balloon go to release the air, and give the craft a gentle push. As the air escapes, it forms a layer of air
between the CD and the surface it's resting on, reducing the friction to allow the craft to move easily.
Vacuum-Packed Boy (You Know You've Been Tempted!)
You can immobilize a boy with a vacuum cleaner and a lawn-sized garbage bag. Choose a sturdy
bag, not one of the thin ones. Drawstring styles are easier to use. Have the child remove his shoes,
climb into the garbage bag, and kneel down. Put the hose of the vacuum down into the bag in front of
him, and have him gather the top edge around his neck and the hose, arranging them as comfortably
as possible, and with his whole head sticking out, obviously! He should kneel along the seam on the
bottom of the bag, so it will conform better to his shape and be less likely to rip. (Having him take off
his shoes helps the bag last longer before ripping, as well.) If the bag has drawstrings, you can help
gather them, tie them right-over-left, then poke them to the inside of the bag and have him pinch the
knot with one hand so it doesn’t loosen. Tell him to be careful of the end of the hose—it's a good idea
to use his other hand to hold it with a cage made of his cupped fingers covering the opening so it
doesn't suck in loose clothing, the bag, or bare skin. You won't get a perfect seal around his neck, and
that’s ok. When you turn on the vacuum cleaner, it sucks most of the air out of the bag, which will
collapse around him. When that's so, ask him to stand up. He can't! If he's small enough, you can
also lift him off the ground to show that he stays in a kneeling position—put one of your hands under
each of his elbows, and lift. To release him, just turn off the vacuum. Be sure to have plenty of extra
bags. You'll have lots of other boys lined up to try it, and even with good quality bags, you'll end up
with holes in them. (You can try extending their life a little with tape, if the hole isn’t too bad.)
Musical Straws: Webelos Maestro 2a or Air of the Wolf 2b
Flatten the end of a plastic drinking straw and cut it into a V shape so that the tip looks like a bird's
beak. It will take some experimentation with how to hold your lips so that when you blow, the top &
bottom “beaks” vibrate against each other and make a sound. For a higher pitch, cut off some of the
straw’s length.
UFO in a balloon (makes a way-cool sound, like a swishy UFO)
Push a penny into a round balloon, then inflate it and tie it off. Get the penny rolling inside the balloon
by moving the balloon in quick circles. You should be able to see the edge of the penny as it rolls
around. (If the penny slides on its face instead of the edge, shake the balloon a couple of times, then
swirl it.) Put it up to your ear and you hear a swishing UFO sort of sound. Hold the balloon very
gently so your fingers don't dent the balloon, as that will knock the penny out of its smooth orbit inside
the balloon.
For a version that the whole room can hear, use a small nut from the hardware store (as in, nut and
bolt kind of nut). Make sure there are no sharp edges on your nut or it will pop the balloon.
Not-So-Musical (OK, Loud & Obnoxious) Soda Cans
Hold two empty soda cans up in front of your face so that the sides are touching but not being forcibly
pushed together. Get your face up close to where they join and blow hard & sharp. Again, it takes
some experimentation, but you will know when you have it right!
The air moving between the cans
produces the vibration that makes the...noise. Notice that it takes some serious blowing to get loud.
Bullroarer: Air of the Wolf 2c
The book suggests tying a cardboard tube to a string to make a bullroarer. Bullroarers are used in
several native or aboriginal cultures, but they aren’t tubular. Generally they are made of a flattened
piece of wood or bone or stone. A simple one can be made by drilling holes in the ends of two large
craft sticks and tying them together with a piece of string. If you add a fishing line swivel near the stick
you use as a handle, it will keep the line from twisting up. Hold one end in your hand and spin the
other around your head. The craft stick will start to rotate, which moves the air around it, which
causes the distinctive buzzing noise. The sound will change depending on how fast you whirl it.
Soft-shell Eggs & Rubbery Chicken Bones: Webelos Adventures in Science 3g
Eggshells and chicken bones are hard because of the calcium carbonate they contain. If you immerse
either one in vinegar, the acetic acid in the vinegar reacts with the calcium carbonate to make calcium
ions and carbon dioxide. You will see bubbles of the carbon dioxide gas starting to form very
soon. (Notice that the egg falls to the bottom of the container when you first put it in. As carbon
dioxide gas bubbles form on the surface of the shell, they cause the egg to float. If you jiggle the
container, the bubbles will break free of the egg and float up to the surface, and the egg will sink again
until it builds up more gas.) If your container is small you may need to replace the vinegar as time
passes, to make sure you still have chemicals free to react. The eggshell softens as it dissolves, and
eventually you will be left with little or no shell left—the egg will be contained only by its membrane. It
will become noticeably larger, because it absorbs some of the vinegar solution through the
membrane. You can dissolve the shell on an egg in about 24 hours but chicken bones take several
days to a week.
---For chicken bones, the thinner the bone, the more flexible it will be. Drumstick and thigh bones
work fine; rib and wing bones are quicker to soften because they're so much thinner. Rib bones will be
flexible enough to tie them in a knot.
---In a Cub setting, you can begin the process at den meeting one week, and bring back the finished
product the next, or you can have each Cub bring an empty, clean clear plastic or glass with a tightfitting lid and you provide eggs/bones and vinegar for them to start their own and take them home to
observe them over the next week.
Class comment: These eggs are not as fragile as you’d think they would be! One leader tells me they
took their shell-less eggs and dropped them from increasing heights, and she was surprised that some
of them bounced rather than breaking. Fun to try, but plan for the mess!
Class comment: if you empty the tube of ink from a neon highlighter into your vinegar, the egg will
absorb the ink and you'll end up with an egg that is colored, and glows under a blacklight.. Something
to try!
Coin Weights: Wolf Adventures in Coins #7
Another coin-weight experiment you can do involves the two different compositions of pennies. During
1982, the US mint started to make pennies from a zinc blank coated with copper instead of from just
copper. These are lighter in weight. Pre-1982 pennies will be the heavier copper ones. Post-1982
pennies will be the lighter zinc ones. During 1982 both varieties were made, so you could collect 1982
pennies and sort them by weight for your coin-weight experiment.
Ivory Soap Clouds
Ivory soap has air whipped into the bar of soap, which makes it float, and makes it easy to cut or
carve. It also makes it expand when you toss a bit into the microwave. Cut a bar of Ivory into 4-8
pieces, depending on how powerful your microwave is. Place the piece of soap in the middle of a
paper plate and microwave it. As you watch through the door, you will see the soap billow and puff up
into a cloud shape. If your cloud spills over the edge of the plate, use a smaller piece of soap next
time. When it stops growing, open the door and remove your soap cloud. It will cool very quickly, and
firm up as it cools. As the microwave heats the soap, the soap softens and the trapped air bubbles
are warmed. When you heat air, the molecules spread out, causing the air bubbles to grow. (Just like
when you heat a marshmallow.) This is what you’re seeing as the microwave works. You can still use
the cooled cloud of soap--it has only changed form.
A Tippe Top From Marbles
A tippe top is a top that, when spun, turns itself upside down. You can make one very simply with 4
marbles and some two-part epoxy glue, applied with a toothpick. Glue three marbles together so they
form a triangle, putting glue everywhere they touch. Glue the fourth marble on top, so it forms a
pyramid, gluing to each of the three marbles below. That's it! When the glue has set, grasp it by one
marble (it will improve your grip if your fingers extend down instead of just holding with your fingertips),
and spin. It will end up spinning on a single marble (not necessarily the one that started out on top,
though.) The assembly turns due to a torque (twisting force) resulting from the friction between the
top and the surface it's spinning on.
