- Current passenger aircraft on 9 flight hours required: 50 - 75 tons of oxygen. Similar amounts of oxygen when photosynthesis produces 25 to 50 thousand hectares of forest;
- hydrogen Atom has very small size (if you take 100 million atoms of this substance, and possess each other, then released the chain length in 1-in cm)
- the human Body by 65 - 75 percent water. It uses the bodies: to regulate body temperature, move nutrients through the body and dissolve nutritional compounds
- the Finest matter that we can see with the naked eye - are the walls of soap bubbles (so, for example, hair or cigarette paper have a thickness in a couple of thousand times)
- Soap bubbles burst 1-3 h, and the nuclear reaction takes place for 1-16 h
- In the normal state its iron is very hard metal, but at a temperature of 5 tees 0 C, it turns into a gaseous state;
