While discussing the Bell Labs wave machine, one of the participants at yesterday's PTSOS2 mentioned a Gummi Bear wave machine made with bamboo skewers and tape.
Here's a link to a video of the device. In the UK, they have Jelly Babies rather than Gummi Bears. (They also have G-clamps. Honestly, isn't that a better name than C-clamps?)
Looks like a winner to me!

I'm thinking... Dots or Crows might be the way to go on this (in the states).

Hey for those who are hesitant to let students play with sharp pointy things (skewers) and candy, you can instead use straws paperclips and standard masking tape. it is cheaper and students don't eat the paper clips. (or at least not man!)
You can also hang it vertically from the roof. I had eight vertical straw machines in my room two weeks ago. Add weighs to the tape at the bottom to provide a restitution force,
This device nicely models the waves of nausea I get whenever I eat Jelly Babies (i.e. Gummy Bears)
