As a young 56 year old - with a long standing interest in science, I love your videos. You always have lovely twists on old concepts and demonstrations. This one underlines yet again how mechanics is so counter intuitive. I loved how the water jets break into droplets through the Rayleigh instability due to surface tension, yet the curved shape of the jets still visible as they fell in your slow motion videos. Obviously a subject for another video. You must be such an inspirational and fun teacher - I do so hope your kids realise how blessed they are ! Long may your inspirational teaching continue for your classroom kids and for us onlookers on RUclips. Thank you.
A friend's teacher in Edinburgh in the '60s was Jim Jardine OBE, a highly respected UK educationalist. A demonstration of his was a bottle of water, with a cork pushed down midway. He then asked what would happen to the cork as the bottle was in free-fall. In those days Super 8 was the best one could do as far as recording was concerned, and slow motion was not an option, but sharp-eyed pupils could see that the cork did not float to the surface during free-fall, but popped up to the surface as the bottle hit the ground.
Your students have a wonderful advantage to have you as a teacher. You always conceive of great experiments to demonstrate the theory of the subject in hand. Allowing the students to participate in most of the experiments is an added advantage.
I love your channel. I was put off physics at school when we spent *weeks* rolling little trucks down ramps and measuring their acceleration rates. I mean, i got it the first time! I have learned so much from you and enjoyed every minute. Thank you!
Teaching 8th grade science I made a very long 'ruler' that was marked in Centimeters with numbers large enough that about 5 meters of it could be framed in an HD smartphone camera on a tripod, and distances could be read fairly accurately. For objects about the size and mass of a softball air resistance had no discernible effect. What was interesting was 60fps close ups of an object being released. First it was difficult to tell when the object's fall actually started. Second, for about 0.10 seconds gravity seemed like it didn't matter. (If you're interested in the ruler I'd be happy to send it to you. I think I now have about 8 or 10 meters, it's laminated, rolls up. It's 11"or 14" wide. Just sitting in my garage since I retired. Maybe you can use it, maybe it ends up in your school's dumpster. It's okay.) When I lived and worked in New York City I did some work in the building right across the street from The Dakota where John Lennon, Lauren Bacall and Leonard Bernstein lived. We'd ride up on the old freight elevator that had an operator who said he liked to go down really fast to feel some weightlessness - of course not much. One day we had to take the passenger elevator. Then we heard what happened. The cable on the freight elevator had snapped. The Otis brakes of course caught it in just a few feet. The operator went home with the jitters.
thanks for your thoughts and comment. I appreciate the offer of the ruler but I'm now retired, still go in and help with substituting and special programs but leaving most of the effort to the younger teachers. when I was growing up, I had an aunt that lived in Philadelphia in building that had the elevator drop. think it was about 3-4 floors. My aunt had just used the elevator shortly before that. end up using the stairs for months afterwards
Regarding the water bucket experiment, this does not apply to you, So, don't try to drink something then jump from a high place, believe me you'll empty your bladder before you hit the ground 😁 Thanks Mr. Bruce!
the puppet did not start in the center.... it balanced out.... now try it with a piece of paper, and a crushed folded up into a ball piece of paper, and one folded like a paper plane.... one kilo of metal, falls quicker than a kilo of drone.... people always like to discount intelligent thought and design.
I came across your channel about half an hour ago through a video on Lissajous figures that you uploaded 7 years ago. I see that this video was uploaded 21 hours ago as I write this. I am happy that you are still actively uploading wonderful educational content
love that video didn't use it. I had to remake this video since the earlier version had copyrighted material in it (music). Learning more about using other people's videos that hard way.
@@YeanyScience Yes, vintage electronics geek RUclipsr Fran Blanche got a strike for including some 'public domain' NASA Voyager footage in one of her videos, as a TV company claimed copyright on it as they used it in a documentary. :O
The secret is to step out of the elevator just before it hits the ground. Thank you Pink Panther cartoons for your life-saving physics hacks :P
oh the things we learn from cartoons. Took me years to unlearn all the "science" from bugs bunny and the road runner. still love them though

Perfect demonstration on Physics Mr Yeany. This is real physics from brilliant teacher.

A fine video by a brilliant teacher. Thank-you!
Teaching teachers. very nice! Julius Sumner Miller would be proud of you, Bruce.
JSMIller inspired a lot of my investigations. Enjoyed him for years

Some excellent demonstrations!
I always enjoy your videos. Thanks for sharing!

Well done, Sir A+
Nice experiments.
Good science. Thank you.
Thanks!
How could you get an inflated beach ball and a bowling ball to fall at the same rate, without removing the atmosphere?
Regarding the water bucket experiment, this does not apply to you,
So, don't try to drink something then jump from a high place, believe me you'll empty your bladder before you hit the ground 😁
Thanks Mr. Bruce!
I only came here to find out if an elevator is falling. With me in it can I jump before impact to avoid taking fall damage?

What happens in free fall? Answer: You don’t get charged 😮🇬🇧💙💙💙💙🙏🇬🇧
You can ONLY learn from someone who builds cannons for raw eggs.
Just watch any video of the astronauts in the space station.
5:00 So disappointed I was waiting on you inserting this clip on the moon :( ruclips.net/video/KDp1tiUsZw8/видео.html

Needs to study acoustics a little bit.
I do the best I can but I have hearing problems
