Description
A nylon string has washers positioned along it at distances proportional to the squares of integers: 1, 4, 9, 16, and 25. When the string is dropped, the washers reach the bottom at equal time intervals. Sound is amplified by the sound board at the bottom of the drop on which the washers fall. ◙
