Two people blow into the ends of a tube, gazing deeply into one another's eyes. One of them has drank more drank than the other, and the Drunk r tells who. 5 prototypes have been made, evolving from electrical boxes, to a surgically modified dog toy, to the most recent aluminum tube. Arduino based, battery powered, USB rechargeable, and good for a whole night of fun. Originally made as a birthday present for a friend, it was such a huge hit at the birthday party, that I kept making more. Circuit and code coming soon.
