Its a pendulum based desktop accessory, its usually 3-4 small metall balls hung by strings.
They are pendulum based but not single pendulum, they transfer force from one side to other side pendulum, and they bounce back and forth.
You see them in movies and its a lil hard to descirbe, but if anyone knows what im talking about please tell me what they are called and where i can buy one.
Thanx

I think you're referring to a Newton's Cradle. I've seen them for sale at Brookstone and Spencer's.

Yes,I know them.There are 5 metal balls hung by silk strings.They are not a pendulum but are transfer of momentum.
I think they are "momentum spheres"
