Description

Geode cracking is a great way to explore science with your children. 

Geodes are another one of natures treasures.

They are formed in the hollow areas of soil such as animal burrows or tree roots.

They  also form in the bubble of volcanic rock.

Over time dissolved minerals absorb into the hollow areas and begin to harden to form the outer shell of the geode.

The minerals will continue to form on the inside and can take hundreds of millions of years before it fills the space in a geode so many remain partly hollow. 

Your geode set will include 6 geodes of varying sizes.

You will also need safety glasses, a hammer or fossil pick and bubble wrap (not included). Your child should be supervised at all times, when breaking the geode and using tools for their safety.
