Geodes were formed millions of years ago when prehistoric volcanoes erupted and gas bubbles were trapped in the lava. The result is a science phenomenon-incredible crystal caverns within each exciting geode. When kids gently hit one of the geodes with a hammer, it will break open to reveal a hidden mineral treasure. Kit includes safety goggles and 15 geodes from 3 different mines which might contain quartz, fluorite, calcite, or even amethyst crystals! Geodes range in size from 1.5"-2". Expires May 5, 2013
