What You Will Need:
plastic shopping bag
empty baby bottle
disposable aluminum oven liner
1 cup white glue
1 cup water
6 pieces of brown tissue paper cut into strips
clear acrylic spray (available at the hardware store)
1 tablespoon liquid dish detergent
1 teaspoon red food coloring
1 tablespoon baking soda
1/3 cup vinegar
To form the volcano, crumple up some of the newspaper and place into the plastic shopping bag. Nestle the baby bottle into the newspaper and gather the opening of the bag around the neck. Tape the bag into place around the neck of the bottle. Now reshape the volcano around the bottle (hint: use masking tape to help hold the volcano shape, spiraling the tape down from a rather narrow opening to a broader base). Place the bag on the oven liner.
Mix the glue and water together in a large bowl. Tear the remaining newspaper into strips. Begin by dipping the newspaper strips in the glue mixture. Make several layers of newspaper strips around the opening and down the volcano (allow the strips to run onto the oven liner). Lay several layers of the strips in a crisscross pattern across and down the volcano. For the final layer, dip the tissue paper in the glue mixture and cbver the volcano. Allow the volcano to dry for several days. When the volcano is dry, spray clear acrylic over it to seal.
Ready to try it out? Place the liquid detergent, food coloring, and baking soda into the bottle. Pour the vinegar in last. The vinegar (an acid) reacts with the baking soda (a base) to produce carbon dioxide. The pressure of the expanding carbon dioxide pushes the foam from the bottle, creating a spectacular lava effect! For a realistic setting, place small evergreen sprigs set in clay around the base of the volcano. When finished, carefully tip the volcano upside down in a sink to empty out the remainder of the lava.
