Ashton showed us how to make a Geyser. He explained to us that if you add Mentos to Coke it creates a reaction, the reaction causes carbon dioxide bubbles to come out of the coke faster. He split everyone into four groups so they could make mini explosions in the class. Lastly Aston took us all outside where he showed us a big one using a large bottle of Coke and Mentos, luckily Mrs Taylor and I were standing up-wind otherwise we would have been showered!
Have a look at his instructions if you want to try this, it was great fun!

Can you see the bubbles forming?
