Take one square of toilet paper and put 1 tbsp. baking soda in the middle of it. Roll it up and twist the ends to enclose the baking soda. When you are ready to present the project, drop the baking soda packet into the volcano, and watch it erupt.
First, add 1/3 cup of baking soda to your magma chamber (bottle). Then add about a teaspoon of dish soap for an extra foaming effect, and top it off with several drops each of red and yellow food coloring. Last, when you are ready for the action, pour in ½ to 1 cup of vinegar and watch the eruption.
Add 1 teaspoon ARM & HAMMER Baking Soda into a small, empty plastic cup. Place this cup into the volcano crater. Quickly pour vinegar mixture into the ARM & HAMMER Baking Soda cup in the crater. Enjoy the “lava” as the volcano erupts.
Put a card under the roll and on top of the bottle top, so you can pull the card and the candies will just drop in at once. Drop all of the Mentos into the bottle at the same time and then move out of the way just as quick as you can. Watch the eruption!
STEP 1: Place your cup in the middle of a tray and cover with sand. Make sure there is a hole at the top for the eruption. STEP 3: Fill your cup just over half full with water, add 3 tea spoons full of baking soda, food colouring and give it a good stir until most of the baking soda dissolves.
Using a hot glue gun, glue your empty spice container into the center of your smaller cardboard circle. Next, scrunch some newspaper or other paper into balls. Glue the paper around the spice container to create the shape of your volcano. Mix some paper mache paste.
Pour warm water and red food coloring into the volcano bottle until filled to the top. Add liquid detergent and baking soda. Pour vinegar in and take a couple steps back. The chemical reaction of the baking soda and vinegar will cause the “lava” to spew from the volcano.
For more of a contained mess try this Volcano:
Place the cup in the middle of the pan. Tear a large sheet of aluminum foil to cover the cup and lay at the bottom of the pan, creating the shape of the volcano. Poke a medium-size hole through the aluminum foil above the cup. This is where your volcano will erupt.
Mix 6 cups flour, 2 cups salt, 4 tablespoons cooking oil and 2 cups warm water. The mixture should be smooth and firm. Add more warm water if needed. Stand the soda bottle in the baking pan and mold the dough around it into a volcano shape.
