I think I saw that too (pun intended ). Still, nothing better than a video from a customer without any special preparation, professionals nearby etc.

There's a video out there somewhere from a TV show where the inventor sticks his finger into one. He does do some preparatory cooling of his hand in a cooler of ice. His finger doesn't even touch the blade before it trips.
