There are loads on the net but EepyBird.com host a few of my favourites, the preparation must have been huge!

We read a bit further and discovered that the reaction isn’t due to a chemical reaction between the soda and the mints. The fizzy explosion is caused by the bubbles of carbon dioxide gas in the soda collecting on the rough surface of the mints.

Anyway the Science Sisters, otherwise known as Freya and Erynn, wanted to try their own version and see if only certain brands of soda and mints worked or if value brands would work too.

Last night, while brushing their teeth, they were chatting about, “What else might work?”. After a rather hilarious rude list of suggestions of things with a rough texture, this is what we decided to try:

1. Cola and Mints
2. Lemonade and Mints
3. Cola and Pebbles
4. Cola and Raisins
5. Cola and Dried Dog Food

What we found:

The mints and pebbles work well, though the pebbles get stuck in the tube, so don’t give such a big fountain.

Both the raisins and the dog food just float and so didn’t work.

The lemonade worked even better than the cola, we think this is because it looked really fizzy even before we started.

Mmmm…there’s also a strange pink glow radiating from Erynn’s head!
