Explore science with this exciting idea

Fun fizzing colours experiment
by Natalie Keeler

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?

Fun fizzing colours experiment!

Step 1

Sprinkle the base of the tuff tray with lots of baking soda.

Dribble the colourful mixture onto the soda, and watch it fizz! Now, why not use different colours to make a cool pattern?
