Can you solve this riddle?
You walk to a beach and a passing bystander has something that interests you. 3 switches. 3 bulbs. 1 ladder in a dark room. 1 bulb doesn't light up (it holds gold). 2 have booby traps and do light up. You can only flip 2 switches, then you have to flip them back. Stepping on the mats in front of the stands activates the trap. How do you get the gold without being trapped?
Get the ladder and go behind the stands. Feel the bulbs, the one that isn't hot contains the gold! ; )
