A Frisbee, pushed by the wind, rolling on a frozen lake in Maine. I repeat: you have to turn on the subtitles to fully enjoy this.

Ah yes, good ol Maine entertainment.

We actually shoveled off a pond over the MLK day weekend and hosed it down. Built a sled ramp for the kids the next day to see how far they could glide. Answer: about as far as we cared to shovel.

If you end up near a frozen lake, this is the one time those dish sleds are actually the exact right tool.

Conservation of angular momentum: not just a good idea; it's the law.

I have to admit, this was *well* past "magic of some type" before I realized these subtitles weren't automatically generated.

I teach chemistry, and at the beginning of each semester in the labs, we show the now-famous chemistry safety video. It was developed in the 1980s and has some weird quirks. It even has its own FB fan page!

But anyway, a few years back, we were trying to get it ADA compliant, with subtitles for the hearing impaired. That’s when someone in the department suggested that YouTube autogenerates captioned! Yay! We don’t have to deal with getting the whole 35 minute video captioned!

That was when we found out that YouTube sometimes autogenerates captions for sounds that are not spoken.

Most notably, the background 80s synth theme music was captioned as “Moo moo moo moo moo moo moo moo moo.”

darkstar, can you share any more identifying details for that video? this one from the ACS maybe? hoping to see the chemistry equivalent of Staplerfahrer Klaus

Inside of the disc says fmsultimate.com, Falmouth (ME) Middle School Ultimate. Right now, lakes in or near Falmouth have about a foot of snow (I live on a lake that spans 3 towns, incl. Falmouth, probably not this lake). Thanks for posting this excellent video.

From youtube: I filmed this while out skating on Great Pond in Cape Elizabeth, Maine. The disc moved entirely due to the wind.

shooboo is not wrong about the subtitles.

I'm wondering, is it the spin that helps it keep its balance, like a top? Does that work vertically as well as horizontally?

I watch a lot of YouTube home machinist content, and I often use captions so I can keep the sound low. Turns out that Google’s algorithm frequently understands the noise produced by making chips of various sorts as [Applause].

Can’t watch the video right now but looking forward to it!

Yes! It's the same principle that keeps the bike upright when cycling (conservation of angular momentum).

This is very good.

Most notably, the background 80s synth theme music was captioned as

...you know, I had never thought about the wheel spin on a bike being the same function as a top, thanks Westringia!

Conservation of angular momentum

Nah, it's just going down a hill.
posted by waving at 10:03 AM on January 23


exogenous, yes, that’s the one!

But I’ve just checked the auto captions, and it appears that YouTube has significantly improved their algorithm, because it’s not “moo-moo-ing” in the synth intro anymore.

That’s progress, but I’m a little sad that Safety Cow has retired to a farm upstate.

The camerawork here is incredible. Following a whizzing, windblown object on an unpredictable path at close quarters, on an icy, bumpy surface... and the disc hardly ever leaves the frame! Bravo.

I kept thinking, "Where is the camera? Are they chasing this with a drone?" Until the other skater came into view and I was like "oh. but still, wow!"

Be still, my heart! PLEASE tell me this is a thing.

That the angular momentum of the wheels is what make a bicycle stable is a commonly held misconception (mostly). Here's a MinutePhysics video that addresses the issue https://www.youtube.com/watch?v=oZAc5t2lkvo.

(Next, ask me why the common schoolbook explanation for how airplane wings work is (mostly) wrong - I feel like I am that guy in the New Yorker cartoon, unable to go to bed, because, somewhere on the Internet, someone is wrong!)

Johnny Quaternion, that's really interesting, thanks! So it's a combination of self-righting steering and conservation of angular momentum that restores the bike to upright.

(Here we have something that's closer to a unicycle/coin rolling, tho -- so I would guess it's a combination of conservation of angular momentum and a profile that stabilizes the frisbee.)
posted by Westringia F. at 11:20 AM on January 23


Does a low-friction surface like ice help the frisbee to roll further, or inhibit it's ability to do so by allowing less purchase?
posted by Paul Slade at 12:48 PM on January 23


It probably helps because by skittering along the ice, it can turn more into the wind and catch more air.

But for science, someone should try this in a large flat parking lot and using rollerblades.
posted by sjswitzer at 12:58 PM on January 23


A lot of the time the frisbee doesn't seem to be spinning very fast. There must be some aerodynamic stabilization going on in addition to any gyroscopic effects, though I'm not nearly smart enough to figure it out.

Hey I've skated on that pond. I wore knee pads because I'm not a good skater. Afterwards we went for hot chocolate.

I grew up in a house on the shore of lake ontario. At the end of the street (about 5 houses down) a creek flowed into the lake - this made for some fantastic skating in the winter, and this video made me miss that place like crazy.
