Abstract.This article introduces the weird world of topology using a coin and string puzzle. The puzzle is based on the ``African ball'', and its mathematical structure is explained. Human levitation and entanglement puzzles involve many uses of topology, and the author believes these kinds of wonderful mathematical ideas may be put to good use in society and government. Presenting students with familiar and appealing educational resources is also important in the teaching of mathematics.
