Glow Brick Blue
The Glow Brick from SUCK UK comes to life in the dark as the pigment inside the light bulb emits a subtle tranquil glow. Glow-in-the-dark pigment is trapped inside a real light bulb which is then encased in a solid block of vivid blue acrylic resin. The mysterious optical effect is caused by light diffracting in the tiny space between the light bulb and the resin giving its surface a polished jewel-like effect. Also it looks really cool. And it's easy to use."
