Question 30

A fictional puzzle: a banana hangs from a string in a long narrow room. There is only a wooden batten. Against the side walls it is too steep to climb; against the end walls you cannot quite reach the banana. The source says jumping would cause a fatal injury. How might the banana be reached and untied? Discuss on paper only. Do not climb, jump, strike objects or damage a ceiling.

Question illustration AI conditional paper reconstruction: for the checked reference, allow an ideal pendulum and a securely supported reachable hand-centre with an assumed small reach radius; the original room supplies no such dimensions.
