MASKING TAPE
directions
step three
Put about 4 cm of muddy
water into a large pan. Put a
cup in the center of the pan.
Use a few marbles at the
bottom of the cup to keep it
weighted down.
Put a rock or marble on the
center of the plastic so that there
is a slight dip in the plastic over
the cup. The plastic should not
touch the cup. Water that
condenses on the plastic will drip
into the cup.
Cover the pan securely with
plastic wrap, but leave a little
slack. Use your finger to put a
little water around the rim of
the pan so that you can make
a good seal between the
plastic and the pan. You may
want to use masking tape to
keep the plastic in place.
