If the physical effects of binge drinking aren’t enough to remind you to slow down, perhaps an external cue–other than a bartender’s threats to cut you off–could help do the trick.

MIT Media Labs researcher Dhairya Dand has created a prototype for a set of ice cubes fitted with LED lights that tell overly eager drinkers when to stop sipping, by flashing an alarming red. Drinkers who ignore the cubes’ warnings will trigger the cubes’ plan B: a warning text message to a friend that their friend might be getting sloppy.
