Re: Explosive demonstration
As a kid we lived next to a 'stately' home with 700 acres of woodland with its own sawmill - lovely old thing all belts and widgets and a 6' diameter saw blade that seemed to take forever to get up to an enormous speed. One day the blade decided to go for a walk and sheered off. It managed to get several hundred yards uphill through densely wooded rugged initially like a knife through butter and then after it struck some rocks and became unstable or bent it just shredded everything in its path for a couple of hundred yards. Its one of the few reasons I'd not advise using rotating masses as energy storage devices!
