HouseholdHacker's video offers seven life hacks that could help you when you're out camping or in a survival scenario. They include how to easily make muddy water clear and make candlelight brighter.
You only need two containers and a piece of cloth for the water filtering trick, but as the video recommends, you should still boil the water just in case.
To brighten a candle's light and protect the flame from the elements, cut an empty soda can into a container for the candle.
These tricks all depend on the materials you have on hand, so they're good to know before you head out into the bush.
