A Science teacher told his class after school, “Whoever can get this egg into this smaller glass bottle will win no homework for a week! The rules are: the egg has to go into the bottle in one piece, and you can’t break the bottle. You can also use anything in the science lab. So, do we have any volunteers?”
A boy raised his hand and the teacher pointed at him. The boy took the egg and looked around the science lab for the things he could use. He saw some writing paper, a pack of matches, some vinegar, a sink, and the glass bottle. Soon, the boy had got the egg into the smaller bottle.
How did he do it?
Note that, without doing anything to the egg, the egg can’t fit into the bottle.
First, soak the egg in the vinegar which softens the shell without compromising the egg. Next, take some of the writing paper and shred it into pieces. Take the shredded pieces and put them into the glass bottle. Take a match and light a fire inside the bottle with the shredded paper. After, take the vinegar-soaked egg and put it on the top of the bottle so that no oxygen may get into the bottle. The fire can’t live without any oxygen, so it will try to suck oxygen from the entrance which the egg is blocking. When the fire does this, the fire becomes like a vacuum. So, basically, the fire sucks the egg into the bottle to try in order to get the oxygen. After a short while, the shell will reharden and that’s how the egg got into the bottle.
