Pardon my inability to come up with the right
term for the item I am thinking about.
Many people have, on their desks, a wooden
frame with little balls suspended on wires. You
pull one back, let it go, and it knocks into the other
balls which are suspended in a row, resulting in
them knocking one another back and forth for
a bit.
I cannot, for the life of me, think of the name of this
thing. Could anyone help?
Many thanks!
Ball swinging / banging / knocking thing-a-ma-jig?
I googled desktop pendulum and some came up in the image search...
Whoo hoo, I found it!
Newton's Cradle!
