I have taught physics for about 30 years. The previous post on the liquid nitrogen is from me. I have many experiences that I believe would be useful for Big Bang. Jevans@rpsok.org One such experience was a competition with another instructor to get the best "hair raising" from the van degraff. After several modifications. Grousing it to the plumbing, having the student stand in a rubber trash can, wearing of a wool sweater, having the device on a martial legged stool with a cafeteria tray in it to insulate it from the stool. I got great success. To the point if sparks storms in the ends if the hair. As the student tired, he moved the can toward the stool to put a bend in his arms. I hollered to try to stop him but it was too late a good 6 inch spark arced from the stool leg to the nearest metal on his body, his zipper. He spent the next 10-15 minutes in a fetal position on the floor. The next demo I chose a girl. Again an arc this time to the under wire. It was time to back off.
