Here's a chance to break open geodes (that are formed by prehistoric bubbles in lava). The kit comes with 15 geodes from 3 different mines so there will be a difference in the crystals that have formed that can include: quartz, fluorite, calcite and amethyst. The kit includes a pair of safety glasses (a must!). We also like their suggestion that you can put the geode in a sock- a much safer way to go with younger kids.  It does not come with a hammer or chisel (the two recommended tools for breaking them open).
