Our Jacobs Ladders are wooden versions of this classic partime toy. Be amazed by its almost magic-like movements, as it falls one way and then the other, switching sides or colours effortlessly. The cleverly'hinged' wooden sections click over each other in a perplexing and ingenious way when you tip the top section over between your fingers. They are irresistible, and almost hypnotic, to fiddle with and make a lovely 'clack-clack-clacking'sound as they move! Great exercise for the grip and the wrists. An intriquing classic wooden sensory resource which offers rewarding movement and sound for little effort. And we have a choice of 2 designs to offer you: Natural or Rainbow. One supplied.
