I mean, can I buy like five of these from you? What would you charge? (I don’t have a 3d printer at hand…)

Yes - just bought a six-pack! Thank you! Holiday presents for my physics teaching colleagues. :-)

It works to use an embroidery hoop and just lift it up quickly

But some of the kids with the wrong perception will think I cheated by giving it a nudge or something!

Have them do it. A colleague made a game out of it. They try to lift the hoop so the ball will hit a target as it rolls across the table. They soon learn to lift it when its velocity is directed toward the target. Target has more points the closer to center.

And TIL what an embroidery hoop is! Yay. :-)

They also are good for this demo. They might have some other purpose, I wonder what embroidery is?

I opened with these in class today and the students had a lot of fun. Thank you Joe 😀

Is it okay for me to put your gif of this in my creative commons forces and motions slides of ideas. Will have credit and link back to you.

Thanks

I would be honored 😀

Ooh, now I want to print one of these! Would you mind sharing the file, or is it appearing on your blog at some point?

cossettej.bsky.social•105 days ago

Just posted links to the printable files here! The files are free if you scroll to the bottom links but I can also print and ship them (hence the "store front" look) 😀
