Logic puzzles require you to think. You will have to be logical in your reasoning.
You have a piece of thick rope which when set fire to at any end, burns for exactly an hour. How will you use it to measure half an hour ?
Set fire to the rope from both ends at the same time and it will burn for half an hour.

|Or you could cut the rope in half|

|it would be easier to put the two ends of the rope together so the rope bends in the middle and then a half hour would be when it burned to the bend. then you could use the other half of the rope for the next half hour.|

|or you could just set it in the middle so it would be 30 minutes when it reaches the end|

|rope doesn't always burn constantly... if you put that in the riddle it would make it better|

|Clever solution! I also thought to just fold it in half, but your way was much more interesting! (though twice as risky!) |
