Boil water using only the power of the sun There's few things more frustrating than wanting hot water and having no easy way to get it. For cooking food, a hot cup of coffee, purifying drinking water or even a quick clean-up – a safe and easy way to boil water is critical. And now it's a snap.
This "solar furnace" looks like a thermos. But no ordinary thermos harnesses the power of the sun to safely boil water like this. It's so easy, even a kid can use it!
It's great for camping, hiking – heck, even pop a couple hot dogs in there on a fishing trip and before you know it... lunch is served! Now, as long as you have sun, you'll always have hot water.
Boil water anywhere without fuel or flames
