I've seen these things for sale on the web. http://www.amasci.com/neodemo.htmlhttp://www.kjmagnetics.com/safety.asp I consistently see the same claims: - they can easily pinch skin, like with a pair of pliers - they can shatter, showering you with high speed shards Are they really that powerful? I mean, I have no reason to doubt the claims, but I find it hard to imagine something so small being so powerful. To pinch your skin like pliers would require a HUGE attractive force. Anyone had any experience? I'm tempted to buy some just to prove it to myself. (Although my original idea has bit the dust. As a joke, I was going to buy several, and carve or draw dots on them and use them as dice, just to get a larf.) "Yeah, that's hilarious Dave, now would you mind driving me to the hospital? I'd drive myself, but with only one working eye... well, you know...."
