A Diet Coke Explosion at St Mary’s!!!

Year 5 have had great fun during science week, finding out about nucleation. This involved creating diet coke and mentos geysers. These geysers are caused by a process called nucleation, where the carbon dioxide in the soda is attracted to the small bumps on the surface of the Mentos. That creates so much pressure that the soda goes flying up into the air quite spectacularly. Mr Clarke volunteered to release the mentos into the bottle whilst Mrs Moran stood at a safe distance taking the photos.
