Alf was the 93rd caller to a radio station contest and was told he would win a car if he could go into a room and come out exactly 30 minutes later. The room had no clock, and Alf was not allowed to wear a watch or bring in anything else that tells time. The only thing he could take into the room was a lighter and a candle in a candle holder (supplied by the radio station) that was guaranteed to burn completely in exactly one hour. Alf was not allowed to use a ruler to measure exactly halfway down the candle. Alf went into the room and emerged exactly 30 minutes later to win the car. How did he do it?
Naw - I see you two are in cahoots to console a poor hubber that was left in the cold, forgotten and ignored. I'll just find a corner and cry in my beer for a few days. And next time answer the puzzle before you do.
