Geodes are rocks that are plain on the outside but can have beautiful crystals on the inside. They are created in the hollow areas of soil such as animal burrows or tree roots. They are also formed in the bubbles in volcanic rock. Over time, dissolved minerals seep into a hollow area and harden into an outer shell creating the geode. The minerals continue to form on the inside walls of the shell, growing towards the centre.

It can take hundreds of millions of years for the space inside a geode to be filled, and many geodes remain partly hollow.

Crack open your own geode to unlock the crystals inside.

A simple and fun project!

  • Supervision required to break open the geode which will require a hammer.
  • For ages 6 - 14 (with suervision)
