Grow a big beautiful crystal and assemble a special platform to display it with a colour-changing LED circuit inside

With this special kit, create your own crystal geode — a round rock containing a crystal-filled cavity. First, cast a plaster geode shell in the mould and then fill it with a crystal-growing alum salt solution. The crystal solution contains an ultraviolet-luminous pigment that gets incorporated into the crystals as they form, resulting in a geode that glows in ultraviolet light.

Display your beautiful specimen day and night! Learn about how crystals form and why the pigment glows under ultraviolet light.

Ages 8+
