A Jacob's ladder is a wooden toy consisting of a series of blocks connected by string, arranged in such a way that when one block is flipped, the others appear to cascade down in a continuous motion. The toy has been around for centuries and is often associated with traditional folk toys. To play with a Jacob's ladder, one holds the top block and tilts it, causing the other blocks to flip over one another in a fluid, almost magical movement. The toy is simple but captivating, demonstrating basic principles of motion and gravity. It is popular for its entertaining visual effect and ease of use.
