One of the oldest toys is the wooden spinning top. The top spins quickly thanks to a string rope coiled around its axis from bottom to top, which sets it in motion when pulled quickly. When the top turns, the colours, forms, and patterns mix together. Each top measures 3"x1.8"x1.8" and is easy to store and carry. This item includes a string or rope. The bottom of the nail isn't really pointed. There are 5 spinning tops in this kit. For the little kids, it's fun to watch, and for the older ones, it's interesting. There are no batteries or electronic components, just old-fashioned know-how and clever design.
