Ultraviolet Flashlight
This LED flashlight is capable of emitting long-wave ultraviolet (UVA) light.
UV Ink Marker
This marker is just like any other, except its ink is only visible under ultraviolet (UV) light. Anything drawn will be invisible to humans until exposed to UV light. The ink contains a photo-initiator which absorbs the high energy photons of UV radiation, but since the atoms in the ink want to be at their lowest energy state, the newly absorbed energy is forced out in the form of 2 new photons, one in the infrared range (i.e. heat) and one in the visible (typically blue/green range). The visible light emitted is called fluorescence.
Uranium Glass
Uranium glass is a type of glass which contains a small amount of uranium, so small that it is harmless to handle. This causes it to glow an intense bright green under ultraviolet light.
Sumatran Amber
Amber is the fossilized resin of prehistoric trees. This reddish amber is from the Indonesian island of Sumatra and is approximately 10–30 million years old. Sumatran amber has the added property of fluorescing bright blue under UV light.
