This science kit is an adventure ready to be discovered! 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". Recommended Ages: Ages 8 and up Availability: In Stock
Author: JonRating: 5 out of 5 starsMy family loved cracking these geodes open. We were really glad we bought the larger kit with the 3 different types of geodes. We were surprised at how different each type looked on the inside. We've opened geodes before and I have to say that these are the nicest ones we've ever cracked open. Beautiful crystals. Thank you Mindware!
