Klutz Maker Lab Rocks Gems and Geodes | Klutz

The colourful rocks you explore with this kit will open up the world of earth science and geology. Kick-start your very own rock collection with the included stones. Then use the crystal powder and mold to grow your own geode formation. Conduct experiments such as building a DIY rock tumbler, measuring pH levels, using the Mohs hardness scale, and more.
