Egg in the Bottle.. Several Variations to Try

Probably the most widely posted kid's science experiment on YouTube but it's the same old example over and over. The egg in the bottle demonstration can be a great investigation of atmospheric pressure used as a STEM activity.Here are some additions that can be made to make it more interesting. Ideas include lengthening the mouth of the bottle, measuring the pressure change. In fact, this doesn't even have to be done with eggs, or how about doing the experiment without any change in temperature, no hot gases cooling or steam condensing to back to water.

Bruce’s videos have a nice innocent ‘early-YouTube’ vibe, which I find pleasing.

Thank you Mr. Yeany! You are my go to source for the greatest science experiments I can share with my own high school students. Keep up the good work.

2:11 It's amazing how much effort goes into filling those jars of pickled eggs. The fact that it can be done so cheaply on a massive scale really gives you a newfound appreciation for them.

Your videos are kind of like that cool uncle you don't see very often because he's always on adventures, but when he comes back he shows you the coolest tricks and wares from his travels. I appreciate how genuine you are to you, Bruce.

Great stuff, Bruce. I hope you are doing great.

Bruce I remember stumbling upon your videos in 2014 or 2015. Either way I was a freshman or sophomore in high school. Thank you, you made learning about science more fun. Thank you for inspiring me and many others.

This is like it was at home when I was a kid. I wondered why friends' homes didn't have flasks, bunsen burners, or other scientific kit.

Sometimes, I think you are having way too much fun with your projects 🤣🤣👍👍

As variations were being shown, I was anticipating or imagining a stretchy latex glove filled with air or water at any moment, a hand in the bottle, if it would seal well enough fingers and all. The indecisive eggs reversing direction were interesting to think about.

Hello Bruce. The eggs seem to be cooked. So it may improve sealing. In case of raw eggs (with rubber to improve sealing). The pressure force would be enough to break it?

Thank you Mr. Yeany for kind and informative videos))

[davidjowett]

Bruce, please do anything you like. But please don't grow up. Your videos, whilst educational, are great fun.

3:26 - Responible. Does it mean indirect cause? 😋

[bramfran]

Thank you! One question, the eggs you are using are boiled and with their shell removed, right?

[stigsandstrom]

@stigkrios What is the diameter of the plexiglas tube?

[zbutter]

Love the video!! thanks for the content!

4:49 now we need to know why swirling water reduces pressure.

Could you pop a huge pimple with this method?
