Foam fountain🎃

It’s fun to do this experiment with pumpkins at Halloween!

Carve a small pumpkin; make the holes quite small and keep the lid of the pumpkin handy. Use  orange food colouring, do the experiment in the pumpkin and as soon as you add the yeast, put the lid back on.

Sometimes we just carve a hole for the mouth, use green food colouring and call it VOMITTING PUMPKINS!
