Forest Fires, Car Exhaust, Space Station
Minnesota experiences over a thousand forest fires every summer. With few roads through the forests, and no fire hydrants, how do they put these fires out before they burn out of control? It's the most unusual construction site there is - the International Space Station. The crew has to live on site for six months at a time and put on special suits before they go outside. The astronauts building the $130 billion International Space Station have some of the toughest working conditions imaginable. So how do they prepare for their demanding jobs? There are over 620 million cars in the world. And every time a car engine turns over, it produces a cocktail of toxic hydrocarbons, nitrogen oxides and carbon monoxide. But when that gas comes out of the exhaust it's clean enough to breathe. So how do they turn poisonous exhaust fumes into clean air?
