Ravensburger Grow crystals and gemstones

The exciting journey through the galaxy of crystals and gemstones can begin right at your doorstep: What do ordinary stones, or minerals, look like under a magnifying glass? With the help of the experiment kit, children can take a closer look at the world of gemstones and test whether all gemstones are equally hard. Of course, sparkling crystal treasures can also be grown in the experiment lab. Impressive crystals can even develop in a self-made geode. The step-by-step instructions show how easy it is. The questions at the end of all the experiments expand and reinforce the knowledge of the young researchers: Are there, for example, crystal salts with different properties? The ScienceX experiment kit "Grow Crystals and Gemstones" opens up the vast, exciting world of minerals, crystals, and gemstones, featuring five different crystal salts and real gemstones.
