This thread is about the many myths we get from survival forums, fiction, and movies. The DIY thermite myth is my starting example. The real part is that it's easy to make from common materials and burns as hot as hell. The myth is that you can use it to eat through the surface of armored vehicles in into the motor where it will then put it out of action. I can't tell you how many books I've read or threads on forums that treat this as a given. Here is the reality: Note that a sentry type of home safe isn't exactly armor plate - it's in reality a medium thickness hardened grade rolled steel bent to look much thicker than it really is. In the video they used a LOT of thermite. There are several YT videos that demonstrate similar results. In one video they couldn't even burn through the thin unhardened steel of a car. Can thermite be useful? Yes. Will it put an armored vehicle out of action like the stories say? No. What survival myths would you like to share? Depending on a myth can cost a like in a real survival situation. This is open to all types of survival scenarios from natural disaster to economic collapse to military invasion to civil war.
