Glow Brick

How cool is the Glow-in-the-dark light bulb? It charges during the day so that it will glow for up to eight hours in the dark. It looks like it would make a perfect night light for your toddler or heck, I wouldn’t mind one myself so I can see my way in the dark at night.
“The real bulb inside is filled with a phosphor luminescent powder. The energy in natural UV light is absorbed into the bulb and then slowly released as it glows in the dark. Its glow will fade overnight but then the Brick recharges once it is exposed to daylight again.”
