A light bulb with a special glow!
Yep - it's a glow-in-the-dark light bulb trapped inside a solid acrylic brick. The Glow Brick recharges from energy in natural sunlight during the day and glows at night. Not only that, it is actually made with a real light bulb! That's right.
The glow-in-the-dark* pigment is 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 - this space forms when the resin shrinks by a tiny amount during the production process. 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. Size is 3.3" x 3.3" x 5"
*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.
