Spy in the glass

A STUDENT has invented high-tech ice cubes that calculate how drunk you are.

Dhairya Dand’s digital cubes measure the number of sips taken, giving an estimate of blood alcohol content that is 80 per cent accurate.

The cubes are made from gelatin and implanted with infrared transmitters, accelerometers and LED lights that change from green, to yellow, to red, depending on how much drink has been consumed.

If the drinker continues despite the red-light warnings, the ice cubes send text messages to friends warning the drinker should be taken home.

The idea came to the student after blacking out at a campus party at the Massachusetts Institute of Technology in America from drinking too much.

The concept began as a one-off invention, but Dand now plans to develop the electronic ice cubes further with a funding grant.
