Thanks guys, I always like to share my work always amateurs but done with great care, Mister Nose I saw it on youtube think a toy is French, after 1 year I tried it and it worked many chances are that the last I was the top, they work with counterweights, magnetized seems this is a pretty cool effect are usually made ??of wood and wire and always use recycled materials in the course of traditional toys we have in my town.
A hug to all
Flavio
