Watch crystals magically grow within each dome as it hangs upside-down in its box - then turn the box over and see the crystals dissolve and disappear over a period of days or weeks. The process can be repeated again and again; every time, the crystals will grow in different shapes. Turn the box sideways and observe crystals dissolving and growing simultaneously!

Each dome comes with its own "cave box" and a fascinating 48-page booklet of cool cave info.

For ages 6 and up.
