Baking Soda, Vinegar, glass container, piece of bamboo to stir, food colouring
Papier Mache Volcano
The glass container was under the papier mache volcano.
Using the hole at the top of the volcano, we poured the baking soda and food colouring
into the glass jar.
We poured the vinegar through the hole in the volcano onto the baking soda.
The vinegar reacted with the baking soda and made a fizzy bubbly liquid.
The liquid bubbled up through top of the volcano.
