So I wouldn’t say most of these are survival tips at all but they sure are handy tips! And handy tips most likely to be relevant while camping or during a power outage. There are two different battery hacks, fire starting hacks and light hacks. I’m not sure I buy this “bleach + water = 55 watt light” trick though! Most of them were new to me so I hope they’re new to you too! And that they work!
