Try this at home

Everyone's alway saying, 'don't try this at home!' we thought we might give this old saying the flick and give you some inspiration for science experiments to try yourself. We would love to see what you come up with! Make sure you share your photos and videos with us via Facebook, Twitter and Instagram.

Cola and Mentos


We’ve all seen Mentos being added to diet cola before, but what’s really going on here? Why do we use Mentos? Why do we use diet cola?

The answer will surprise you, and is more simple than you might think!
