Gadgets…..We all love them. This particular little gem is the Glow Brick, a cool little cube that glows. Where are the cords?
No cables protude from the crisp, clear, acrylic block that completely covers a simple bulb. But leave it out in the light for a few hours and it brightens up to cast a colored glow. Use it as a nightlight or even better, it let's people think you are at home at night when you go out. Glow time at night is eight hours.
