A bit of a science experiment now… I’m not going to go into why this works I’m just going to tell you how to do it and it’s really fab!

You will need:

  • A two litre bottle of fizzy drink (diet coke works best according to my sources!) ideally refrigerated
  • Five extra strong mints
  • A rolled paper tube slightly larger than the mints, but smaller than the hole in the top of the bottle and a small piece of card

What to do:

  • First of all go outside and keep the kids well back
  • The plan is to get all the mints into the pop bottle as fast as possible so you need a way of dropping them all together
  • Pop five into a tube and hold them steady over the bottle with a piece of card beneath
  • Then, very carefully open the bottle, trying not to let it fizz…Remove the card and release the mints quickly and all together, and retire to a safe distance
  • Boom! The drink should turn to foam and erupt out of the bottle up to a metre high
