Physics of toys- Cup Flyers // Homemade Science with Bruce Yeany

Plastic, foam or paper cups can easily be made into indoor flying objects that demonstrate the force that causes curveballs, golf balls and many other examples to curve due to the Magnus effect. A variety of sizes and variables can can this simple experiment into a fun and educational learning experience.

[@thescalex9849]

Mr. Yeany I found your channel a few days ago and I've been going through your videos, watching a few every day, and I have to say you're awesome. You're enthusiastic, and that's something I think, overall, a lot of teachers and professors don't give their students/colleagues. In each and every video I can see how excited you are by all these concepts. Keeping the enthusiasm for science and physics alive in middle and high school is soooo important!! Keep it up!

[@jashann]

I wish my professors taught even half as passionately as you do.

[@glenngriffon8032]

I think if all teachers in the US' education system were as passionate and enjoyed their work as much as you our public education system wouldn't be a mess.

[@ejej_shej7958]

Glenn Griffon i agree

[@WhatsTheTakeaway]

According g to some government officials, if teachers were paid more now, they would perform better in the future.

[@angelhelp]

One problem you didn't include is the difficulty of teaching students who do not speak English (at least here in the USA). The problem is only worsened by policies that enable the students to avoid learning English. They graduate functionally illiterate, don't care, and neither do their families seem to care. The answer is NOT to hire bilingual teachers and office staff. The answer is to compel these students to have a proper command of English, just as we would have to learn proper French if we planned to live in France.

Mr.Yeany, thanks for these awesome videos! as long as there are teachers like you around, we will be all good!

[@TienHuynh5312]

thank you for making these videos! One of the best physics teachers that I know

[@GeneralSzadek]

Oh man, you´re such a good teacher^^ your kids can be happy to have you.

[@bertusackerman]

You have no idea how I'd have enjoyed you as my science teacher! Awesome videos.

[@YeanyScience]

thanks, I appreciate hearing it

[@mikewashere9660]

Big time kudos to you Sir, this country, whatever country you're teaching in, has a huge honor having you instruct young minds! You're a credit to those who teach! God Bless you!

[@smallbee1234]

You remind me of my favorite teacher in high school, Mr. Renouir. I struggled with math until he came along and taught with this same passion. To this day I credit him for me making it through high school. Oh, and by the way, he was also a police officer for APD! Thank you for being a great science teacher. I sure your students will never forget you, much like I will never forget Mr. Renouir.

[@YeanyScience]

nice comment, thank you!

[@TheInfamousTacos]

These have become my new favorite videos to watch. I wish my teachers taught me more like how you teach! Keep it up!

[@YeanyScience]

Wow, thanks

[@vickyxun9062]

Thank You Mr.Bruce, it really helped my son for his science project, thank you so much!

[@KatrinaGressett]

This is really fantastic! As a newish physics teacher I'm always looking for inexpensive demos to create for my classes. Thanks so much for a great channel.

when no one around..... all teacher start doing some thing similar to this. moral of the story. never stop having fun

[@YeanyScience]

I'm not sure about other teachers but this is what I do. You are absolutely right. This is my 40th year teaching, I could have retired 4 years ago but didn't, why? because I enjoy and love what I do. Thanks for your notes.

[@j5892000]

se you are the kind of teacher i love. you make it fun. when teacher taught like this i learned the most.

[@Powd3r81]

your kids are in good hands! Seeing as how the first time I learned about the magnus effect was in my incompressible flow class in college, when I was 21 years old, your kids are defintely in very good hands! Way ahead of me

[@bisheshshrestha2656]

Thank you for this wonderful video Mr. Yeany! Using the led bulbs to trace the path of the cup was really creative

[@VC27]

You Sir, are the kind of teachers that are desperately needed the world over. Respect.

[@mikefule330]

The most useful part of this as a physics demo is when you fire it on a vertical axis. It curves sharply to the side but drops very quickly to the ground. This proves that the distance covered in the "normal" orientation is because of the lift generated by the rotation, rather than just by the ballistic effect of being catapulted. Excellent.

[@b1lbotbagg1nz17]

I've found myself binge watching your videos. Definitely going to show my kids this one as a home project!

[@Alles-Is-Natuurkunde]

I love how you laugh each time you launch one. It is that which makes teaching physics fun… enjoying it yourself 👍

[@YeanyScience]

thanks, I really do enjoy this myself

[@carmelpule6954]

Brilliant demonstration. That is called the Magnus effect and at the start of the century they tried to propel a ship with it for if those cups are rotated and placed in the wind they will create a side or a lateral force. Mr Bruce Yeany, congratulations, you should show that demonstration to young footballers for that is the method to score a goal from a corner shot or a free kick with a lot of players acting as a barrier for the shot. All young footballers should know about the Magnus effect for they could score if they only know how and where to kick a ball. That should be taught to all children for playing with a ball, is not just play , but it is pure science and if one models it with mathematics well one can have so many artistic trajectories. Well done Mr Yeany.

[@patrickthomas8282]

I am an elementary science teacher in Boston. Just found your videos. Great resource to add to class instruction.

[@Graeme_Lastname]

All my years and I have never before seen that. Thanks fir the info. The physics is easily understandable but the idea is, for me, new.

[@jffqnn]

Went out and bought the stuff to make these so me and my Nephew, as well as His friend next door, can participate in this activity, Love the Cup Gun, I may just have to invest some time into making one myself!! Thank You Bruce for all of these Awesome Videos, Makes life More Interesting when you see the Eyes of your loved ones Light Up and want to know more!! Sincerely, JeffQ

[@uncletacosupreme7023]

Mr. Bruce thank you for these videos. I have children and I always try to find fun stuff to do with them. I want them to question things and investigate on their own. These are fun ideas. I am starting with the paper plate speaker.

[@facu16666]

I would have liked to have a teacher like you! God bless you!

[@DJ-lc5fe]

Your one of those science teachers that your students will always remember.

[@cheeseweasel69]

Really liked the long exposure effects. Very cleaver and simple way of showing the flight path which I had never considered. Shows that sometimes all the technology we have can sometimes make us forget the more simple solutions. Seems like there is a lesson in there somewhere haha Thanks for the great video as always.

[@GendefectX]

like how you have fun with all of your experiments. makes me smile, thanks :)

You are a wonderful teacher. The extra time you put into your lesson plans and making the lesson interesting is admirable. I loved having teachers like you. Teachers who loved what they learned, and love teaching what they know. I can see it in your videos. Good job. Please keep up the good work.

[@YeanyScience]

Thank you Banana, I appreciate your thoughts

[@richarddblythe]

I just discovered that if you add an additional cup to each end, the floating phenomenon is much longer. Very good video Bruce! Thanks for making science so tangible for kids....wait...everyone!

That's interesting. I have not seen that done before. I will have to show my nieces when I next see them. A nice video explaining how it works.

[@thecuriousone9342]

This guy is the best teacher, reminded me of my high school days

[@shinjisan2015]

great touch with the LED and long exposure, really shows how it works.

[@diegofloor]

It makes such an interesting trajectory. That sharp spike, it almost feels like it goes backwards for a moment before resuming forward movement.I think air resistence kills that large linear momentum the cup got from the rubber band, but the cup's rotation never stopped so it continues to accelerate it forward. But it's odd that it stops, I would have guessed that it reduces velocity until a specific value and stays there.

[@VeteranVandal]

You are a very good teacher, man.
