Science: Volcano

 


Part of our Japan unit involved researching natural disasters (specifically volcanoes).

We designed and made a volcano from paper mache, painted it green and made it explode by mixing vinegar, baking soda and red food dye. Messy - but loads of fun!

To make the paper mache paste you will need water and flour.
Mix 1 part flour to 2 parts water.
It needs to be of thick consistency and without lumps.

To explode the volcano, pour the vinegar into the cup at the top of the volcano, then add teaspoons of baking soda.
To create the red effect as seen in the photo above, I added red glitter to the vinegar.
