Homemade Science with Bruce Yeany
Homemade science is a collection of classroom tested ideas, suggestions, projects, and experiments that I have used in teaching physical science for the Annville-Cleona school district in central Pennsylvania. I have taught science for 41 years and retired in 2018 due to bad knees. My intention is to share these ideas with other teachers or anyone who has an interest in science. I have found that designing and building my own equipment has taught me more than any course that I have ever taken. I hope that you consider trying this for yourself.. I also share and show some of these ideas at workshops, science conferences, or inservice presentations. I can be reached by email at [email protected]

This is awsomest, would this be a music class or design and teachnology
I think you'd love science and futurism with Isaac Arthur. He talks about space based applications of things like this
Fascinating stuff as always!
EXCELENT!!!!! thanks for sharing, can you tell me where did you buy the Strip?, regards
Bruce the kinda guy you bring a cup of tea , open the door , and wake up in hospital with a bandage on your head😂
This is a great project that we are trying to do. We are having a problem finding a motor. Where did you get yours?
The Earth is flat with Firmament, and stationary.
I hear cups of water screaming
Excellent. This video was perfect for my child's second grade physics class.
Gostei, show
This centrifugal force is clear to me, but why sand corns center in rotating water in a bucket?
8:17 thats a creative perspective.👍
I trying to do that experiment at home to show it to my children, but i don't get a Baby Doll to a float. What pressuere did you use and what size of jet?
Love this. I will not be able to think of cycling the same ever again...
This is how the workers catch Durian fruit with burlap sacks from heights of 80-165 feet. The sack snaps like a whip when they catch them kzread.info/dash/bejne/nZOhldiTfNC6hbw.html
It's like a miniature form of artificial gravity.
This is perhaps the most popular experiment in the world.
Bit of parametric resonance going on, especially when liquid. Energy is also being expended in the elasticity of the knot end and string.
Science!
4:56 the free fall phase is amazing! What I love in free fall, is that raising object are also in free fall...
You are now Certfied Centripetal force bender. 😅
With an 18ft (~5.5m) string the tray is travelling ~8.2m/s. One revolution ~2.1 seconds.
LOVE the more in depth videos please do more
Hey Bruce! I'm just starting out my career as a science teacher and finding your channel has made me so happy. I've been watching every video! Thank you so much!
I'm happy to hear that, my original goal was to show other teachers ideas that I found useful
Hej Bruce, your students must love you 🙂 I definitely would have back in the days if I had you as my science teacher. But no, there were mostly boring folks… 😞
Thanks , for yours vudeos. One simple question. When you release this construction for a "free" fly... seems the center of rotation is somewhere near to water. So, probably there is not enought centifugial acceleration to keep water in place. But it steel there. How it selfbalanced ... ?
This was an epic show of skill, you make it look easy. This is one of those experiments that can mess with people's minds, it can look fake or unreal even when you **know ** this is real. In fact, if you hadn't shown those two fails I would have been one of the first to jokingly mention "glue is still an option" in one way or another haha.
Great video, I am relieved you didn’t fall off the stadium as you were swinging it round! You will need a hammer thrower with higher speed and strength to see what string length can be achieved😁
When I taught this topic, I also made some circular saw blades out of paper and attached them to hand drills with magnets. They worked brilliantly for cutting pieces of foam. Just keep your finger clear because that would be a nasty paper cut.
Bruce, you are simply one of the best. Thanks for all the knowledge and laughs you've shared over the years. You are a true hero, good sir🤝
miraculous!
I haven't watched you in a hot minute but you truly do make science fun.
It would be good if you could measure the speed of rotation and capture several pictures of the horizontal angle at different speeds of rotation, and then draw conclusions on the horizontal angle of the liquid surface as a function of the speed and the length of string.
I do this trick with my kids in the hammock to give them a ride
Maybe the slate was cooled in that particular spot. As the water cools down, so does the air inside.
I'd love a good youtuber battle of this
I'm intrigued about the physics of bringing it to a halt without spilling. Why is it easier with shortening the string? It's there a physical reason it's impossible to bring to a stable halt at 14 ft? Is the system stable as it 'coils in' around a cylindrical axis (it looked like it).
Probably because your arm can only move so far to dampen the oscillation.
I would love to see the lager one again and the string progressively getting shorter and then eventually stopping it like the short one. 🤔 Edit :never mind I saw it
It's wonder at least one YTber gets it right with Centripetal force. Because ever other YTber is so retarded to call it centrifugal force 😂 great job 😎well done 👌
Love it! Nice spinning skills, reminds me of poi or diabolo a bit.
Crazy you can throw it, I'm gonna try juggling this at some time
I hadn't seen this one before this, it would be interesting to see the change from the concave of earth gravity to the convex of centripetal 'gravity'
Bruce! Did you used ever take your demonstrations to elementary schools in Reno Nevada in the early 2000's? If I found your channel all these years later, wow.
I have been to Nevada a few times, Reno once but not for related activities. I've done demonstrations for various schools and science teacher conferences, mostly on the east coast.
Make one with students on a swing set!
What a Badass
Turkish tea seller tray, they used to do this to get attention and sell more tea
Like I know how this works but I can't help myself with feeling the fear of the water falling if one spins it wrongly
Very cool. As a kid, I would do this with a stretched out metal coat hangar and a penny
I love the idea of having the students build their own apparatus to push find limits. I have been using a trick that I learned in junior high. Take a wire coat hanger and stretch it out into a long diamond shape. If necessary bend the hook so it points straight up when the coat hanger is hung from the top of the diamond. Now the fun part. find an older penny with the Lincoln Memorial of the back. Balance the penny on the hook and try to get it spinning around your index finger. Once it is spinning it is quite stable. Then the trick is to stop it without the penny falling. It takes some practice but it is quite impressive once you get the hang of it. Most coins should work (unless they have a hole in the center) as long as they have one face that is pretty flat. Also, some coat hangers have a bevel cut on the end that may have to be filed flat. Once I get the penny stopped I shake the hanger to prove the penny is not glued on.
Thank you Bruce
