Cut the pizza into 11 equal slices with a wrist watch

Tools: (1) A wrist watch and (2) a normal knife

Goal: Slice a pizza into 11 equal pieces

Cut the pizza when the watch's hands are overlapping by manually advancing the watch.

This problem was posted on Quora, but I'll refine it for more fun:

Answered by Predrag Minic:

  • Take a wrist watch.
  • Position the watch hands to noon and put in the center of pizza
  • Cut in the direction of the overlapping watch hands
  • Advance the watch until next overlapping of its hands
  • Repeat steps 3 and 4 until all pieces are sliced

The key is that the hands of a watch overlap in 11 different (equally spaced) positions.
