" A graduate student has invented digital ice cubes that detect when someone has had too much to drink. Dhairya Dand, who is currently studying at the Massachusetts Institute of Technology, has developed the product that warns when you&amp;#039;ve had too much alcohol, or a lot in a short space of time. The idea came to Dand after he drank too much at a party and woke up several hours later in an emergency room after blacking out. Dand created a video to explain his invention and experience of making it, which has gained thousands of views since its release last week.  He explained that the cubes are made from gelatin and fixed with infrared transmitters, accelerometers and LED lights that change from green, to yellow, to red depending on how high your alcohol intake is.  The accelerometers measure the amount of sips taken and give an estimate of the person&amp;#039;s blood alcohol content. If the person continues to drink in spite of the red light, the ice cubes are able to send text messages to friends warning them. Dand said in the video: &amp;quot;I &amp;#039;remember&amp;#039; having three drinks. Seven hours later, I [woke] up at the hospital. &amp;quot;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.&amp;quot; Although it started as a one-off invention, the 23-year-old now plans to further develop the electronic ice cubes.
