Here we are in the grinder again, and the firefighters from the on base fire station are about to rip a car apart for us.  They peeled back the top of the car, cut the supports for the windows out, and broke up the windshields, basically destroying these cars.  After they were done with the show, they showed us how to use these inflateable bags to lift up things that are really heavy.  They have one bag that can lift up a trolley!  They were all really nice, and the demos they put on were really neat.
