Jacob's ladder (also magic tabletsChinese blocks, and klick-klack toy[1]) is a folk toy consisting of blocks of wood held together by strings or ribbons. It is "a toy that does some very weird things."[2] When the ladder is held at one end, blocks appear to cascade down the strings. This effect is a visual illusion which is the result of one block after another flipping over. It may be considered a kinetic illusion, where the blocks appear to change position when they do not.
