MIT student Dhairya Dand has developed a clear, glowing ‘ice cube’ that flashes different colors as alcohol consumption increases. The cubes contain a colored LED, sensors and a battery, all of which are encased in a substance that won’t dissolve and won’t change the taste of your drink. An accelerometer keeps up with the number of sips a person takes and calculates the level of intoxication. The cubes turn from green to red when it’s time to turn off the tap.
Dand came up with the idea after a rough night of imbibing—he thought he’d only had a couple of drinks until he woke up in a hospital and learned he’d blacked out after far more. To save others from a similar experience he figured a bright, visual cue would get the message across that it’s time to slow down. If one keeps drinking the cube goes a step further and texts a designated friend to step in for a little extra convincing. To up the fun factor, the cubes flash in time to ambient party music.
Dand told ABC News he only spent $50 on the prototype, and as a believer in open sourcing he’s willing to share the technology with other inventors.
