Hey everyone, I really do love sharing detailed and hard riddles, so here is another one: there is a room with a lightbulb inside. Outside the room, there are 3 switches. Only 1 switch opens the lightbulb. You need to figure out which one. You can flip the switches on and off as many times as you want, but you can only go in the room to check once. How do you find out which switch opens the lightbulb? ***Answers: turn the first switch on, wait a while, turn it off, and then turn the 3rd switch one. Now go in the room. If the light is on, it is the 3rd switch. If it is not, feel the lightbulb. If it is hot, it is the 1st one, if it is cold, it is the second one. Nice hun? :) *** PS, should I keep putting the answers below, or give you guys time and put it on a different post?
