I went to a jaws of life practice thingy once. They have these little pads they use to lift stuff that fill with air and expand, and they have this huge scissor looking thing that they cut the cars with and they had another big tool thingy I can't remember. I think it was all hydrolic, but I can't remember. The coolest part was when they sprayed adhesive on a window and barely tapped the corner of it and the whole window shattered but stayed in place.
