Communicate with others without having to speak… According to Lou van’t Riet, in Belgium potable is slang for date-able and not potable means not date-able!
I designed pants with conductive fabric above and below the knee areas. When you cross your LEFT leg over the right, you can signal YES (potable) with a green light. Cross your RIGHT leg over the left leg, and signal a NO (not potable).
For the final prototype, the lights on the belt were changed to blink every half second to be more noticable.
