Smart ice cubes warn drinkers when they’ve had too much
MIT researcher Dhairya Dand has developed a set of electronic ice cubes that can monitor a person's alcohol intake and change colour from green to red to tell them when to stop.
Each cube is comprised of a coloured led, an accelerometer, IR receivers and a battery, which are moulded into an edible, waterproof jelly.
With one cube of each colour (green, yellow and red) in a glass, the light changes depending on how much alcohol a person consumes and how fast.
If they then keep on drinking after the red cube flashes, a text is sent to a designated friend to ask them for help.
