first right answer gets best answer:

you have a 1-minute string fuse, and it burns unevenly, fast then slow, slow then fast. you have one match, no clocks, no other timing devices.

how do you time *exactly* 30 seconds.

  1. fold it in half and burn it from the bent end when its all out 30 sec is up


  2. start timing 30 seconds in ur head when the fuse starts burning =]

  3. cut the string length wise and burn either end, this will account for the different densities that make the string burn faster or slower.

  4. Put both ends together and burn both sides at the same time.
