The US Army had an A bomb blast simulator (without the radiation, of course) that was implemented by discharging tanks of oxy and acetylene (they had been manifolded and controlled remotely) into a very large bag. Troops were assembled the appropriate distance away and this thing was touched off electrically. I wasn't there so I don't know the distances etc. but was told it was impressive beyond words. Would thump you in the chest like a mule kick and tumble you. Closer, of course, it would kill so everyone was away when the valves opened. I think they were afraid static electricity might pop it prematurely.
Wish I could have seen it. Better than an air/fuel bomb as no nitrogen dilutant.

Worked at a refractory brick manufacturing plant, (45lb pitch bonded calcined dolomite for use in Basic Oxygen Steelmaking Vessels.) The workers used to do a similar thing with soccer ball sized plastic bags. Great dust shaker but the cardboard wick soaked in kero had me worried safety wise. Not wanting to spoil their fun (and to get in on the act myself) made up detonators out of match heads packed around a single strand of fine iron wire. These were attatched to one end of a long twin strand cord and sealed inside the bag of oxy-acetylene. The fork lift came in handy as both a source of battery power and a sufety shield. Even convinced the manager that letting a few larger ones of these of in the kiln building would be a good way of shaking the dust out of the place. After a while the small plastic bags got a bit ho hum. So we went larger. 56lb plastic liners from concrete style paper bags were employed to great effect. We ended up with a good demonstration of the power of fuel and oxygen. A heavy duty lidless 44 gallon drum (55g US) was stuffed with two of these bags and inverted over two bricks. The resulting bank and flames were very impressive (the local airforce base got the blame for sonic booms that night). Being dark we couldn't see what happened to the drum. Shortly there was a clatter and then a thump. Exploring by torchlight revealed the base of the drum which had been blown out and now resembled a chinamans hat, nearby was the body of the drum, split at the seam and wrapped completely around itself. Just as well that wire was a long one. regards Paul. Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Please do NOT send "unsubscribe" messages to the list address.
