Positively the best way to turn the temperature negative, this ice tray will make icy batteries in different shapes to make any drink electrifying. Simply fill one side the tray with water and stick the other side on top, then place them in the freezer, and as the water expands it'll create transparent 3D batteries.

You could even fill them with fruit juice to make different coloured batteries. So why not recharge your batteries with ones of the icey variety? They look great in all manner of drinks, and will postively cool you down during the hot summer months. - A.D.
