**Breje Diana, Festeu Cristina, Hara Paula, Vidrasan Emanuela ** To perform this experiment we need a boiled egg, bark, matches and a bottle with his mouth wider.
 * //__Atmospheric pressure __ //**

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.
