Atmospheric pressure

video

To perform this experiment we need a boiled egg, bark, matches and a bottle with his mouth wider. First light match, is inserted in the bottle and let them burn. Bark boiled egg and place over the mouth of the bottle. After put the eggs, match is extinguished, and the eggs begin to pass the mouth of the bottle until it reaches the. Because the eggs covered the mouth of the glass to match the fire consumed all the oxygen in the bottle, and after it was extinguished. Explanation: Because of the lack of oxygen pressure and body weight decreases with pressure acting on the outside glass egg that "leaking" through the mouth bottles.

Unexpected! first time I saw the picture I thought that the eggs will be thrown out, but in the end I noticed that because of the burning glass eggs of oxygen was absorbed, even if it is greater than "mouth" of container, with the pressure that is formed. just wait to try it !!!!!

It´s cool, but you should have shown what happens if you don´t use matches
