    Fizzy Elf Laboratory

    November 19, 2018 By Emma Vanstone 1 Comment

    We’ve been having more Elf themed Christmas science fun this week with this Fizzy Elf Laboratory.

    All you need is baking soda, vinegar and food colouring!

    You might also like our ELF STEM Challenges where you can build a new shelf for the elf, make a parachute for an elf and lots more!

    Fizzy Elf Laboratory

    What 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 getting in 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 them 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 makes 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?
