Glow-in-the-dark* pigment trapped inside a real light bulb (just like the ones
you have at home). Then the light bulb is encased in a solid block of Acrylic
resin. The mysterious optical effect is caused by light diffracting in the tiny
space between the glass of the light bulb and the resin, the space forms when
the resin shrinks by a tiny amount during the production possess. The polished
surface gives a jewel like quality to the object. In a darkened room or at night
the Glow Brick comes to life with a tranquil and subtle glow emanating from the
pigment inside the light bulb.
*The technical term for the
glow-in-the-dark is "photoluminescence" this is a process in which energy
absorbed by a substance is released relatively slowly in the form of light.
