This is a pretty cool trick. The video shows how to make a big ball of glowing ice. Basically you stick a simple LED into a water balloon and freeze it with the wires sticking out of the end of the balloon. When it’s frozen you simply peel the balloon off of the big ball of ice and attach a 9-volt battery to the LED. Bam! You’ve got yourself a cool ass glowing orb of frozen light to impress your friends. It’s pretty fun, though not nearly as fun as just throwing the frozen water balloon at your friends. If you’ve never been hit by a frozen water balloon, let me tell you, it’s a riot. Even better if it’s glowing.
