Q&A for How to Get an Egg Into a Bottle

Because you're putting matches or candles in the bottle, it's best to use glass. The heat from the flame from a match or candle may melt the plastic.

Turn the bottle upside down. Make sure the egg is positioned well in the bottle neck. Continuing to hold the bottle upside down, hold it over your mouth and blow hard into the bottle. Quickly raise the bottle up and the egg will immediately pop down out of the bottle onto your mouth. The reason is that you added so much more air pressure into the bottle than the pressure outside the bottle. The pressure inside balanced with the outside by expanding the egg out of the bottle. A second method for removing it is to put the bottle in a cold ice chest or the fridge or freezer for several minutes to get the bottle air cold. Then remove the bottle upside down, and wait patiently several minutes.

The matchstick burns inside of the bottle consuming all of the oxygen. This creates a vacuum, causing the egg to get sucked into the bottle.

When air heats up, it expands, so some air is forced out of the bottle. When the air cools, it creates a vacuum and pulls the egg into the bottle. You could likely also do this by running hot water over the outside of the bottle to heat the bottle and the air inside, then put the egg on top.

Boiling an egg takes about five minutes and then getting the egg into the bottle takes about two minutes.

First, you need a clean dry bottle with an opening and neck slightly smaller than your hard-boiled egg. Set a piece of paper or other flammable material inside the bottle, and light it with a match. Make sure the material doesn't go out too quickly. Right after lighting the material, place the hard-boiled egg (smaller side down) into the opening of the bottle. The warm air will suck the malleable egg into the bottle and plop it to the bottom.

No. A boiled egg is soft, the raw egg will be a liquid. Also, because the shell is hard, it will not get sucked in.

Nothing actually happens to the egg when it goes inside the bottle. You can still eat it after getting it out.

Yes, it would. Just be careful not to burn yourself.

It's a fun and popular science experiment that is often used in school. It teaches students about air pressure, eggs, bottles and heat.

In order to put another egg in, you have to light another match which will likely cause the previous egg to ignite. So, I do not suggest using more than one egg.

It is the physics of air pressure. When you insert the lit paper or birthday candles, the air molecules inside the bottle heat up. Heated molecules become excited and spread out, making the air less dense, and some of them will even escape from the bottle.

Nothing will happen. The air-pressure change inside the bottle is not strong enough to break the shell and pull the egg and shell through the neck of the bottle.

No, the neck opening on a wine bottle is not big enough to allow a chicken egg to pass through.
