MIT student Dhairya Dand has invented digital ice cubes with built-in flashing LEDs which warn you when you have had too much to drink. He came up with the design after blacking out at a party and ending up in hospital following a drinks party at the Massachusetts Institute of Technology.
Dand, 23, made the cubes from gelatin and came up with a simple LED color-coded traffic light system to warn drinkers when it is time to slow down.
The cubes have green, yellow and red LED lights, a battery, an infrared transmitter and built-in accelerometers to detect how quickly someone is drinking. The lights go from green, yellow and then red when people are drinking too quickly.

For the first drink the flashing ice cubes beat with green light. On the second drink they flash orange. After two drinks, the cubes turn from yellow to red — signalling it’s time to slow down or stop drinking.
If you keep drinking, the transmitter inside the cube sends a signal to your cell phone to text for a designated driver.
