Sample
At the beginning of the experiment, I prepared the materials, including a boiled egg, a glass bottle whose neck is a bit smaller than the egg, and some hot water. With all the things prepared, the experiment began.
The experiment is designed to prove whether air pressure really exists.
Sample
First, I removed the shell of the egg. Then I carefully poured some hot water into the bottle, and shook the bottle gently. After a few minutes, I poured out the hot water. Just at the same time, l quickly placed the egg on top of the bottle. To my amazement, the egg squeezed into the bottle at once.
After the experiment, I can draw the conclusion that air pressure indeed exists, and it is very powerful. It is the force of the air that pushed the egg into the bottle.
Activity 1
