GETTING AN EGG INTO A BOTTLE |
YOU WILL NEED: an egg a towel(毛巾) a glass bottle with a 25-30 mm lid(盖子) some hot water |
★Boil the egg for 4 minutes until the white of the egg is hard but the yolk(蛋黄) is soft.Let it cool.Then peel it. ★Pour the hot water into the bottle.Put on the lid,cover in a towel and shake it well. ★Take off the lid and pour out the water. ★Put the egg in the opening of the warm bottle. ★ After a few minutes,the egg is pulled into the bottle. |
HOW IT WORKS The egg is pulled into the bottle because the hot water in the bottle makes the bottle warm,and the air in the bottle gets warm too.Hot air's volume(体积) gets bigger and takes up more space than cold air.When the bottle cools again,the air inside it goes back to room temperature,so the air pressure inside the bottle drops(减小).And the outside air pressure pulls the egg into the bottle. |
