UNICEF has invented a machine that turns human sweat into water, I know sounds gross but there is a need for it. The machine is called the Sweat Machine and was created in Sweden. The machine can turn human sweat into fresh water, and is much needed in parts of the world.  This gives me an idea, maybe I will get this machine and marked my sweat, althouth there may not be a high demand for my sweat, but there may be some celebrity's that you may want to buy a bottle of their sweat.  There is always someone to take an idea to the next level.
