Fizzy Erupting Hearts

Fizzy, bursting with colour and a little science thrown in! This is such a fun and interesting activity and always renders different results which makes them even more beautiful!

For older children you can discuss the vinegar is acidic and the baking soda is a base and the reaction neutralises them. For young kids just let them enjoy the magic of the reaction!

These also make great gifts for family and friends! I know we will be sending some out!

What do you need?

Cut out hearts on watercolour paper or card * see note

Food colouring (any colours you like)

1 bottle vinegar

Baking soda

Pipettes

Then...

Mix a few drops of food colouring with 1/4 cup vinegar.
Repeat for all of the colours you want to use.
Lay out the hearts on a washable mat or aluminium foil.
Use a spoon to sprinkle the baking soda over the hearts.
Then using a pipette drop the vinegar and food colouring solution onto the hearts and watch the magic happen!
Let the hearts dry fully. You may need to tip off excess paint.

Note: watercolour paper yields the best results.
