Volcanoes

You Need:

Fizzy pop and bottles

Mentos mints

What You Do:

Take a bottle of diety fizzy pop and one to five fruit flavoured or mint Mentos.

Put Mentos in the bottle.

Stand back.  Pow!

For an even better effect, dig a small hole for the bottle so that it’s sticking half-way out before you put the mentos inside, and pile up mud around the sides to make it look like a real volcano.
