In front of you are several long fuses. (maybe we are back to launching rockets with burning fuses.. who knows...)
You know they burn for exactly one minute after you light them at one end.
But the entire fuse does not burn at a constant speed. For example, it might take five seconds to burn through half the fuse and fifty-five seconds to burn the other half.
With your lighter and using these fuses, how can you measure exactly 45 seconds of time?
