Outback Survival Feedback

Hello,I have just read your survival tips and found it to be a good common sense artical that would ensure some ones chances of survival,But one tip regarding starting a fire could cause serious injury,Never Use Metal to mix pottassium permanganate (condy's crystals ),using metal objects,(knives,spoons etc ), it can cause an explosion,Wood glass (watch face, bottle )anything but metal,and grind the mix as if using a mortise and pessal, it wont always explode but when it does it can cause some nasty injuries,especially to eyes,I found out the hard way,so hope this helps others avoid my mistake,,keep up the good work,,,Gummy
