Here's a nice one:
you have two ropes, each of which takes one hour to burn completely. both of these ropes are nonhomogeneous in thickness, meaning that some parts of the ropes are chunkier than other parts of the rope. using these nonhomogeneous ropes and a lighter, time 45 minutes...
...if you look at one of your ropes and cut it into pieces, you have no clue how long any individual piece will take to burn off.

Light rope1 in both ends and rope2 in one end simultaneously. When the flames on rope1 meet, 30 minutes have passed, and rope2 will burn 30 more minutes (from one end). At that moment, light the other end of rope2, which will then burn for 15 more minutes.
