I don’t know about you, but unless you want to host a real crazy party, then this is for you – the LED ice cubes. A dozen of these $19.90 waterproof color changing ice cubes will shine all seven colors of the rainbow or change colors from time to time, giving your plain vodka on the rocks a whole new glow. Interestingly enough, the batteries can be replaced so you can always use them as standard ice cubes even when the battery has long died. What worries me is something going wrong and having the battery leak – now that’d be a disaster. Hopefully the “durable plastic” it comes in works as advertised, otherwise you could be serving poison to your guests.
