Make your own Geodes

This fun science kit will teach you all about geology but the best bit is that you get to make your very own geodes from scratch.

To make your geodes, you need to make a plaster of Paris mould. Once hard, you dissolve some crystals in water and add your mould. Leave for the prescribed time and before you know it, you’ll have your very own geodes to show off to your friends!

Adult supervision needed.

This kit is made by World of Science and you can make two geodes from it. It is for children aged 8 and over. Colours of geodes may differ from the colours shown in the image.

Not suitable for children under the age of 3 years.
