Subject: Atomic Trampoline - Whatever happened to these?
I can't find any listings online. The one referenced below says that it's out of stock.
Does anyone know where these might still be available?

You drop a ball bearing into each tube side by side. The difference is quite striking. It works for the same reason as "regular" glass does. The amorphous metal has no crystal structure, so it cannot absorb energy easily by creating and moving dislocations.
