Drinking can be dangerous when you don’t drink responsibly. If you can’t stop by yourself, use the power of LEDs to help you know when to stop drinking.
MIT Media Lab researcher Dhairya Dand took matters into their own hands and created these LED ice cubes after a night of alcoholic drinks resulted in a blackout that put him in the hospital. They detect alcohol and flash colors based on the amount of drinks that have been had and track the number of sips you take as well as the total time spent drinking.
When the LED ice cubes go beyond the red level, a text message warning is sent to a friend. This could really save lifes if the friend is a good one and gives a ride.
