Fizzy, Frozen Easter Eggs

Modified: May 20, 2024 · Published: Apr 4, 2014 by Emma Vanstone · This post may contain affiliate links · 1 Comment

Baking soda experiments have always been very popular with my children. They are such fun, fizzy reactions that can be used in many 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’.

Once you’ve made your fizzy easter eggs, don’t forget to take a look at my other Easter themed science activities.

Fizzy Baking Soda Eggs

What you need

Egg-shaped mould

Water

Food colouring

Small toy

Baking soda

Vinegar

Instructions

Add some food colouring to the water and pour into the moulds.

Add 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 hacking 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 that is a great introduction to chemical reactions.

The science bit

Vinegar (an acid ) and bicarbonate of soda ( an alkali ) react to neutralise each other. This reaction releases carbon dioxide, a gas that causes the bubbles you see.
