Survival gear can be expensive, heavy, and prone to breaking down.
Having some gear around is a great idea, but relying on it too much can be a mistake, especially when it comes to filling an essential need like food preparation.
DIY Aluminum Can Burners
Though you might have stoves and burners around for this purpose, this is a low cost project for creating an alternate source of heat for cooking food and sanitizing water.
These can burners, also known as hobo stoves, give you a quick, cheap, and easy flame to cook with.
Having this knowledge under your belt could be your ticket to staying fed in a pinch or just help out as a cheap way to create a mobile burner for many other reasons.
Here are two methods for creating a cheap and easy alcohol fueled burner out of aluminum cans.
Method 1: The Homemade Outdoor Luxe
