Description

Make a real fizz with these ice volcanoes best suited to outdoors

Resources

The supplies you need for making ice volcanoes are:
small bowls,
balls that will sink,
plastic wrap,
a mixture of water and baking soda. I didn't measure, but if I had to guess I'd say it was about a third baking soda. I also added food coloring
some room in a freezer
vinegar

Instructions

mix the water food colouring and water together. In a bowl put in the ball, a golf ball works well. This will create the crater of the volcano so choose the bowl and ball size carefully. line the bowl with the plastic wrap, this will help to remove the ice volcano once you are reday to use it. Put it in the freezer.

once set take out side and add a drop or two of vinegar and watch them errupt.
