Blowing up a camper trailer with tannerite

This old camper was on my property when I bought the place a few years ago. Nobody wanted it because it was in horrible shape. We cleared a spot in the woods, dragged it in place, put 4.5 lbs of tannerite in it, and videoed the result. The camper roof flew about 50 feet in the air and landed in a tree top - it was awesome!
