Tape the cup to the plate by rolling a piece of tape onto the
bottom of the cup and sticking it on the plate.
Cover the plate/cup structure with aluminum foil.
Poke a hole in the foil at the center and cut strips out to the
circumference of the
cup.
Fold the foil down and
tape it to the inside
of the cup.
Pour 2 T of water into
the cup and stir in 1 T
baking soda. Stir it
until it dissolves.
Measure 2 T of
vinegar into a
separate cup.
Pour the vinegar into the baking soda and water solution and
observe your “lava” bubbling up.
Carbon Dioxide is a gas that forms when the vinegar reacts with the baking soda. The gas builds up
and causes the solution to bubble up and over the cup. This is similar to a volcano. Sometimes a gases
build up inside a volcano and cause it to explode violently. Other times the lava of an erupting
volcano oozes over the sides slowly intead.
