hey remember the sit'n spin??? Well this is a new and imprived version that seats two. It's bigger and better and give you the option of accelerating faster!
Ever wondered how the sit'n spin works ... well the mechanisms are quite simple. The small wheel at the top of the toy is rotated to tighten the torsion spring at the base of the toy, upon release of the small wheel the base rotates in the opposite direction. Once again newtons law is at work here!
