Here is a puzzle that a camp counselor asked me. But unfortunately he forgot to tell me the answer as he said he would at the end of the camp. I checked online at lots of sites but none had this brain teaser. So i hope one of you guys can pm me the answer. Here is the brain teaser. There is a very long bridge that you have to cross. But, in the middle of the bridge is a Troll. The troll sleeps every three minutes for three minutes(He wakes up three minutes after he sleeps). When he is awake he can see anyone on the bridge. If he sees you on the bridge he will send you back to the original side you came from. If it takes you exactly three minutes and one second to cross the bridge(always, no matter what speed you travel), how do you cross the bridge?
