Boil water on the go without having to build a fire.

This is if you need to boil water in a container that won’t survive being put over an open flame. The Heatstick heats up through chemical reactions and screws right onto your water bottle, keeping the water contained and clean. Each one contains enough fuel to boil a couple gallons, making it great for the outdoorsman or survivalist. The downside? It’s not exactly cost-effective, retailing for about $460. Check out the video of it below.
