It looks a bit like magic, but the Glow Brick is actually smart glow-in-the-dark technology.

The acrylic block encasing the light bulb is completely sealed, so no changing batteries or plugging anything in. Just ensure that the Glow Brick is left where it can store up some power from natural light during the day.

At night, you'll get the full effect of the mysterious blue glow, great for mood lighting or a handy cordless nightlight. It'll make a great talking point and we've got plans to use them in pumpkins at Halloween for the ultimate portable spooky lighting.
