Oxy/acetylene Balloons
by nitrox
If you want a real bang - mix approximately equal mixtures of oxygen and acetylene into a balloon and tie the end off. Either use a petrol or gunpowder fuse, just make sure you have got enough time to get well back! For a bit of excitment, put two or three balloons under a drum, 44 gal (200L- Australia) and a chook or two, add a twenty foot petrol fuse, ignite, stand back, watch drum reach about 200' and see a very startled chook learning to fly! Good stuff!by nitrox
