The bottle swallows the egg experiment
Witness the wonderful power of science
Family laboratories no. 17
In order to be able to reveal the phenomenon of science in life, to disseminate scientific knowledge, to stimulate interest in and exploration of science, and to give the spirit of science its roots in the hearts of every family and fellow student. The school has set up a “family laboratory” column, which provides a platform for students to demonstrate themselves and to enter the scientific world。
The bottle swallows the egg experiment
The bottle swallows the egg experiment
Welcome to our family laboratories. I'm lujoran in third grade (3), and today we will be exploring an interesting and surprising scientific experiment — a bottle that swallows eggs. Behind this seemingly magical phenomenon lies the science of atmospheric pressure。
I. Experimental material
- a goggles
- an egg cooked and skinned (sure that the egg surface is smooth and easy to observe experimental phenomena)
- a large bottle
- a flammable note
- a box of matches or lighters
- an ashtray
Ii. Electronic steps
1. To wear protective glasses and provide safety。
2. The skind eggs were placed in a bottle and found to be stuck。
3. Carefully ignited the note with matches, and quickly placed the burning note in the glass bottle, moving quickly to prevent the flame from extinguishing。
At this point, care is taken to keep the surrounding environment safe and away from flammable items。
4. Next, the skind eggs are lightly placed in the bottle, ensuring that the eggs are fully covered and that a relatively sealed environment is created。
A moment of miracles
Students, watch carefully! You'll see the eggs are moving slowly into the bottle, as if the bottle really had life and was swallowing them. Over time, the eggs were gradually inhaled into the bottle, and eventually, the sound of a “thock” fell steadily at the bottom of the bottle. Isn't this amazing scene making you look like a fool
The principles of the experiment were revealed
Why would a bottle swallow eggs? The scientific rationale behind this is that atmospheric pressure works. When a burning note is placed in a bottle, it consumes oxygen in the bottle and produces gases such as carbon dioxide. As oxygen is consumed, the total amount of gas in the bottle is reduced and the pressure is gradually reduced. At this point, the atmospheric pressure outside the bottle remained constant and remained standard. Because the internal pressure of the bottle is smaller than the external pressure of the bottle, the external atmospheric pressure is like a powerful big hand “pushing” the eggs into the bottle, thus creating the wonderful phenomenon of the bottle swallowing the eggs。
Summary
Through this simple and interesting experiment, not only is the magic of science, but the concept of atmospheric pressure can be understood more intuitively. Students, try this experiment and feel the beauty of science. Let's explore the mystery of science and start a scientific journey full of surprises
Sweet tip
Carnation: in the course of the experiment, take protective glasses, make sure that the matches are extinguished and then disposed of, make sure that the bottles are intact and do not explode with heat。
