Here’s one way to keep your cold drinks interesting, toss in electricity! Alright, in a slightly more harmless manner than it actually sounds. Each one of these ice cubes has an LED light and a battery that can handle being frozen and thawed over and over. To use them, just pop them in the freezer to cool down. Then turn them on before putting them in your drink. You can make them glow just one color or flip through all six. The batteries will only run for 12 hours continuously though. You can purchase them for £7.99 or about $13 from I want one of those.
