I didn't watch the clip, but I'm guessing this is right
Look for the Devil's cola bottle I believe they market it as. I think they retail for about $395 a bottle or something mad like that - I honestly can't remember though!
The key points though is that the bottle can be hit against hard surfaces so that the spec. can see that it's solid, then a coin dropped in and swung around. It's pretty much self working and is pretty crazy.
Not for everyday performance though with such a high cost!
Many people do mention learning about the principle in school though, I didn't personally, but we're different in the UK, instead of teaching us to smash stuff they teach us how to drink tea correctly and how one might consume that viscous ambrose we call a crumpet!
Man, you americans are missing out. Go find a british store and buy some crumpets. They're AWESOME.
