This may be the equivalent of a Breathalyzer in a cup. MIT graduate student Dhairya Dand created glowing ice cubes, which not only synchronize to the beat of ambient sound, but also measure how much you are drinking, according to Popsci.com.
Encased in edible jelly, the cubes' circuitry tracks the number of sips taken by using an accelerometer. They calculate how impaired the drinker is based on a timer. By changing color, the cubes alert you to slow down your consumption, and if you continue, they send a text to your friend.
The idea was born in the aftermath of a very bad drunken night Dand had. Watch the video above to see just how these ice cubes work.
Would you use them?
