Thrusting an Egg into the Bottle and Taking Out Using Science

Today man can’t move a step forward without the help of science. So, science is one of the main subjects in the school curriculum but students take it as a dry subject. Therefore, it is our responsibility to prepare the students mentally for science study with useful skills. In this post,I am sharing the method of “How to thrust an egg into a bottle having a narrow opening than the size of the egg?”. This is just science nothing other than this. Students will learn about the airpressure through this egg thrusting experiment.

Science Magic of Thrusting An Egg Into The Bottle and Taking Out

This Science Game (Thrusting An Egg Into The Bottle and Taking Out) can be used to demonstrate the effect of pressure i.e, atmospheric pressure in relation to the external or internal pressure of the container. Students can also use to trick their friends at Home, School, etc. 
Now let’s do it Step by Step-

Necessary materials -How to Thrust an Egg into a Bottle with a small hole?

  • A bottle with the big opening (less than the size of an egg)
  • A big sized egg of a hen or a duck
  • Some pieces of paper.
  • 5-10 ml kerosene oil
  • Matches

Preparation – Set up of this experiment

Boil the egg for about half an hour and remove its rind.

The Game of Thrusting an Egg into The Bottle and Taking Out – Fun Science Idea

Presentation of the game/magic – Thrusting of an Egg into the bottle:

The bottle will look funnier if it is given the appearance of a man. Everybody will feel the fun when the egg much bigger than the opening of the bottle gets thrust into it. For, this sprinkles a few drops of kerosene oil over the piece of paper and put them into the bottle. Set fire to them with the match sticks. When the fire gets extinguished after the combustion of the pieces of the paper, place the egg vertically on the opening of the bottle. Provided that the smaller (pointed) part of the egg should be placed in the opening. Just after a little while, the egg will enter into the bottle producing a sharp sound. Isn’t it great fun? Certainly, everybody enjoys great fun when the egg gets into the bottle. But the game becomes more fun when the egg cannot be taken out of the bottle. Then how to take it out?

Method of Taking Out an Egg from inside the Bottle that has a smaller opening than Egg:

Fill some water in the bottle and upset it. The ashes or pieces of paper will come out. Now, bring the bottle again to the upright position and blow strongly through its opening with your mouth. After blowing, quickly slant the bottle. The egg will come out of it. Wow! what great fun! Isn’t it?

The scientific reason for which the egg gets thrust into the bottle:

When the quantity of air inside the bottle decreases, the pressure decreases too. Consequently, as the external atmospheric pressure is higher than the internal one, it pushes the egg into the bottle.

The scientific reason for which the egg comes out:

The bottle was full of air from the very beginning i.e. before the air was pimped into it with the mouth. The air pimped in this way was additional. As the additional air dashed with the base of the bottle and got pushed in the opposite direction, it helps to push to the egg out of the bottle.
