I think I must have been having an off day today. My wife's paper shredder had jammed up, so gave it a good clean. Then sprayed the cutters with lubricant, turned it on and the top half jumped a couple of inches in the air. Apparently the bang was quite loud. I really must remember that the propellant is inflammable and that the on/off switch sparks...........
Any one know how long it takes for the hairs on arms to grow back?
