How it works: The dissolved carbon gas, which is what makes it fizzy, forms bubbles. The microscopic pits on the surface of the mint that we added provide nucleation sites for the carbon gas bubbles to form much quicker than normal. All that gas takes up more room than the liquid, so it has to escape out of the bottle - upwards! Fast!

Outdoor fizzy science
Today I bought 8 litres of fizzy drinks. Neither K nor M like fizzy drinks at all, and A and I aren't particularly bothered by them, but since we weren't planning on drinking them that didn't really matter. It was, once again, back to our Science Experiments book to 'Make a soda shoot'. We tried it with 4 different drinks, diet cola, cola, orangeade and lemonade. Here's what the lemonade looked like:
