Fizzy, Frozen Easter Eggs

Baking soda experiments are always very popular with my children, it’s such a fun reaction and can be used in lots of creative ways.

We’ve made baking soda ice before, but this time I added a little twist by making the ice Easter egg shaped. We also made some without the baking soda and hid a toy lizard, which the girls had to ‘rescue’.

What you need

Egg shaped mould

Water

Food colouring

Small toy

Baking soda

Vinegar

Instructions

Add some food colouring to water and pour into moulds.

Add about a tablespoon of baking soda to the ones you want to be fizzy.

Add a toy if you wish.

We played with the ice eggs first. I asked the girls how they thought they could ‘rescue’ the lizard. First they tried to hack away at the ice using a spoon, when this didn’t work they wanted to put it somewhere warm. I suggested pouring warm water over the top instead.

 

Once the lizard had been set free, we poured some vinegar over the baking soda eggs, which fizzed brilliantly.

 

This is such a fun and easy experiment, a great introduction to chemical reactions.

The Science bit

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.
