Fun fizzing colours experiment

This experiment combines baking soda, vinegar and food colouring – and the effect is explosive (but not messy, we promise).

We love this idea because it only need a few ingredients from the back of your kitchen cupboard. And the results – and giggles – are definitely worth it.

Why not try our DIY lava lamp experiment next?
