Christmas Science Experiment

Here is one of the most colourful science experiments you can try at Christmas. MATERIALS:⠀ - Baking soda⠀ - Food colouring - Water - Ice tray - Vinegar - Hand wash INSTRUCTIONS:⠀ (1) Add a few drops of food colouring to baking soda, add a little bit of water and mix (2) Repeat with different colours.⠀ (3) Add the mixtures to your ice tray⠀ (4) Freeze until solid (5) Lay them out in a deep bowl (6) Add hand wash to vinegar and mix (7) Pour the mixture over the frozen shapes and watch them fizz (: Mix up the foam to create colourful art SCIENCE EXPLANATION When we mix vinegar and baking soda, they react and produce a gas - carbon dioxide. We added soap into the mix. So the gas blows bubbles, creating a lot of foam.
