Nostalgic Toys ~ Jacob's Ladder

A Jacob's ladder is a folk toy consisting of blocks of wood held together by strings or ribbons. The Jacob's Ladder folk toy, also known as 'tumbling blocks' dates back to the Pilgrim times in America.

 When the ladder is held at one end, blocks appear to cascade down the strings. However, this effect is a visual illusion which is the result of one block after another flipping over.
