Glowing Crystal Geode

You can create your own crystal geode - a round rock containing the crystals. First, cast a plaster shell in the mould and then fill it up with some aluminous salt solution that contains ultraviolet-luminous pigments incorporated into each individual mineral as they form.

When you expose this guy's glowing under UV light at night time or day time he'll look absolutely amazing because of all these beautiful colours from different minerals mixed together coming forward through out its entire body; giving it such unique characteristics not seen before on any other object ever created by nature or mankind.
