Here's a great activity for little and big kids alike! Remember to always supervise young children.
MAKING THE VOLCANO SHELL: To make the basic shape of a volcano, place the bottle in the middle of the cardboard base and run strips of masking tape from the lower sides of the bottle to the base to secure on the board.
Run strips of masking tape from the top of the bottle to the base in a radial type pattern. Continue all around the bottle until a volcano like shape is formed. This will be your frame.
To make the glue, mix 3 parts flour with two parts water and stir to combine. Coat the strips of newspaper in the glue mixture and drape on the masking tape frame. Layer until covered to your satisfaction (at least 2 layers). Leave to dry overnight. When dry, paint the volcano as you please.
MAKING THE ERUPTION: Carefully pour vinegar into the bottle. Add red food dye and detergent.
Using a funnel, carefully add Bi Carb Soda in one go and watch the volcano erupt.
