@NYC Toy Fair 2009Kistal, these are quartz-looking crystals you grow yourself. The crystal growth can be sped up and slowed down depending on the temperature, they grow in 2 to 7 days, but can grow longer/bigger for as long as you keep them in the solution (or until it evaporates). They are beautiful and depending on the kit you can also learn about crystal growth experiments onboard the International Space Station.
