I still enjoy watching physics demonstrations that I would have learned in high school even after getting two degrees in physics and 30+ years since high school graduation

You aren't alone. It is so easy to watch when someone like Bruce is teaching. We need more teachers like him. You know he is most student's favorite teacher.

You will always have my support on this channel

Thank you, appreciate it. I still have more to show.

So that's how they get submarines to submerge, who knew. LOL Thanks for the upload

I'm not sure if you explained it in the video. I had to think about it for a bit, and realized that the AIR in the diver is being compressed, allowing more water in. At first I thought "I thought liquids were nearly incompressible. How is he compressing the liquid?" You're not. Thanks for this video.

very good, I did explain the basic in part one If you are interested, I explained the basics on the diver in part one kzread.info/dash/bejne/mKht2sGOdanFaNI.html

Regardless of your age, you can learn something every day, I certainly do.

Beautiful

always great

Awesome!

I remember doing it as a kid.

Gracias gracias gracias ❤❤❤

Amazing Bruce. As always. Can we have "serial divers"? I mean a larger bottle with a smaller bottle inside of it with a diver inside the sallee bottle? Would both sink?

Have you considered using teflon tape to help seal the treads of the bigger plastic containers with their lids?

@YeanyScience

the big containers actually have small gaps to keep them from being airtight, , adding tape, making paper gaskets, rubber gaskets, with a little success. I found the plastic bags gave me the best results

Part III Can you make a diver that flips once for head down as it’s going down. Flips again to go back up, head on top?

interesting idea, I'll give it a try

I'm a little confused as to why the Christmas tree ornament works as a diver. Does it have an opening in it through which water and air can enter and leave it?

@YeanyScience

yes, there is a hole at the bottom

I didn't catch the explanation how it works. Maybe it's more fun to guess. I'm guessing that liquid is non compressible and the air can be compressed. So the liquid does not change in volume under pressure but air does reduce in volume. So the diver gets more water inside of it under presure and becomes less buoyant. Now why the depth is a factor is maybe more complicated. I'm guessing the air will start resisting compression more at higher pressures and the diver can't full up with water as much and it stops sinking. Am I talking nonsense?
