Written by Are you ready to sprinkle a little science magic into your holiday celebrations? My Fizzy Elf Laboratory is the perfect way to introduce little scientists to the principles of chemical reactions.
All you need is need baking soda, vinegar, food colouring, test tubes and some curious elves!

Fizzy Elf Laboratory
You’ll need
Test tubes or containers
Test tube holder
Baking soda ( bicarbonate of soda )
Vinegar
Red and green food colouring
Eco glitter – optional
Funnel
Safety note:
Children should wear safety goggles to prevent vinegar from getting in their little eyes.
Set up an Elf Lab
Use a funnel to neatly add a teaspoon of baking soda to each test tube.
Add a few drops of food colouring and some eco glitter.
Give them all a good stir.
Get ready for the fizz
Add a few drops of vinegar to each test tube and watch the mixture fizz!
Why does this happen?
Vinegar (an acid) and bicarbonate of soda ( an alkali ) react together to neutralise each other. This reaction releases carbon dioxide, a gas, which is the bubbles you see. The carbon dioxide bubbles mixed with the food colouring make a lovely foam!
Extension tasks
What could you add to make the foam thicker?
What happens if you use more or less baking soda?
Why does this happen?
