BBC Earth Crystal Aquarium: Colorful Crystal Growing Kit for Kids Ages 6+
The BBC Earth Grow & Discover Crystal Aquarium lets children grow colorful crystals in blue, green, purple, and yellow that can reach up to 4 inches tall inside a reusable plastic tank. Designed for ages 6 and up, this STEM kit includes crystal-growing rocks, a growth solution, and a 2-in-1 guide created with scientists. It takes five simple steps to start, and once done, the aquarium can be cleaned and reused for other nature finds.
What Comes in the Crystal Aquarium Kit
The set includes one crystal aquarium measuring 8.25 by 5 by 1.75 inches, four crystal-growing rocks, one packet of crystal-growing solution, and a two-in-one poster and guide. Stickers depicting real cave structures such as stalactites and stalagmites let you customize the tank and learn about natural formations.
How the Growing Process Works
In five simple steps you can start the crystal growth. The crystals emerge in shades of blue, green, purple, and yellow. The guide explains the science behind underwater crystal formation, so you understand what is happening as the crystals climb upward. Because the chemicals require adult supervision, an older helper should be nearby during setup.
How This Kit Supports STEM Learning
This kit encourages observation, experimentation, and exploration. The guide, developed alongside BBC Earth scientists, covers crystal growing and underwater rock formation. After the crystals are fully grown, you can clean the aquarium and collect rocks or minerals from nature to display or store. This reuse aspect teaches sustainability and the scientific method.
Is the Aquarium Reusable?
Yes. Once the crystal growth is complete, you can clean the tank thoroughly and use it as a container for other rocks and minerals you find outdoors. Some people turn it into a desk organizer. The reusable design reduces waste and extends the play value.
