Bruce’s videos have a nice innocent ‘early-KZread’ 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.

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.

Also, is anybody else contemplating a pressure differential-powered egg mortar now?

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.

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

homie having a great time

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.

Love it! Thanks Bruce.

Well done as always!

Bruce: "I'll just light a series of small fires in my home office. Don't worry, it's for science!" ❤❤ 😂

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.

The best of KZread!!!

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

Love the video!! thanks for the content!

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.

I'll have to try that

A sudden alcohol whoosh could be another variation to play with to create a vacuum, or with a snorkel/barrel and capacitor bottle, the blowdown might allow more time before losing the strongest vacuum. If a burst diaphragm were somehow "easily" designed to hold pressure momentarily after the initial evacuation of hot gases, but then break when an object strikes it, a vacuum cannon based on your "grape bullet" bottle example might be fun to try, or illustrative in some way. But yes, it would only be fun if it were easy enough to make or embellish.

​@@YeanyScience I tried a latex glove filled with water and a gallon cider jug prepped with a little methanol. After the sudden whoosh of ignition, the glove just a few inches away was quickly placed over the neck opening,. Apparently the force was too strong and the glove ruptured quite suddenly as a slug of water blasted into the bottle - an interesting sound effect if nothing else. After a second failure, a stronger 5 mil XL nitrile glove did the trick and with some force the large water balloon glove was pulled back out of the bottle by hand by the tied end without breaking. In a second trial the glove didn't want to come out of the bottle and broke as I was trying to tug it out carefully.

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

Hello Bruce. In thia video you've measured the vacuum pressure. Is it possible to also measure the volume decay inside the flask/bottle?

@YeanyScience

Ай бұрын

yes, instead of attaching the hose to the straw to the egg, I attached it to a rubber stopper and put that at the mouth of the flask. The problem is knowing at what moment you would have the greatest amount of thermal energy pushing the air out. Tried it a few times, and got about the same reading as with the egg in the bottle.

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

@YeanyScience

Ай бұрын

swirling the water helps to dissolve the ammonia gas into the water faster, same reason as stirring to mix something faster

Ahh 5:46 finally says it. I saw that screen and never connected it to the water swirl 🤦‍♂️

Could you pop a huge pimple with this method?

For those people who don't understand or are young, explain to them what PSI means.

Gravity is creating the air pressure which pushes the egg toward the lower pressure (heat)

They do that with tires to put on a rim and fill the tire with are at the same time..
