Student creates ice cubes that keep tabs on alcohol intake

A student has created digital ice cubes which warn people when they've had too much to drink.

Dhairya Dand came up with the products - which contain gelatin and are fixed with infrared transmitters, accelerometers and LED lights that change between green, yellow and red depending on how much a person has consumed - after ending up in hospital following a night out.

The Massachusetts Institute of Technology attendee has created a video explaining what his digital ice cubes are all about.

In the clip, he says: "I 'remember' having three drinks. Seven hours later, I [woke] up at the hospital.

"Three weeks later, I built glowing ice cubes that beat to the ambient music ... The [electronic] circuit keeps track of time and number of sips."
