After blacking out from drinking too much and waking up in the hospital, Dhairya Dand got creative to ensure it never happened again:
I made self-aware glowing ice-cubes that beat to the ambient music. The electronics inside the ice-cubes know how fast and how much you are drinking. The cubes change color from green to orange to finally red as you keep drinking beyond the safety limit. If things get out of control, the cubes send a text to your close friend using your smartphone.
Emil Protalinski is impressed:
What do you do when you have too much to drink? Most people whine and groan. Some get a hangover. Others declare they will never drink again! … [N]ot only did Dand go way beyond what most people would do to make sure he never has a terrible night of drinking again, but he actually created a device that would help him out. All he has to do is remember to bring and use the ice cube.
