It’s a Swing Wing!
“It’s a WHAT?”, the commercial inquires. An appropriate exclamation for the Swing Wing, as it almost touches effectively upon the sense of bafflement one experiences upon viewing it.
What I have to say about this item was neatly summarized in my response to the loved one who shared it:
D: So…enough people really thought this whiplash-inducing device was a good idea to get the thing patented?
“Mommy, I want to play.”
“Ok darling! Go thrash your head violently and whip your own eyeballs. Here’s a cat o’ nine tails on a hat.”
C: Evidently yes! In fact, cut & paste that hypothetical conversation alongside this video and you’ve got yourself a tidy little SWS post, eh?
Also from Transogram, their patent-pending Bouncy Running Scissors and Kooky Box O’ Glass Shards. Just kidding. Or maybe not…I don’t know what else they made.

Hahaha! This is not a good way to teach children how to appear sane. Imagine this thing becoming the new trend in a school playground. Everyone injuring themselves and others nearby. It’s crazy!
I suppose someone looked at the hula hoop and figured out there was a gap in the spinning body part market.

I recall a few spinning body part toys. Hula Hooping was the only “athletic” thing I truly excelled at. And I had a ball on a string that went around the ankle for the purpose of “skipping.” Hmm…what the heck was that called…oh yeah! SKIP IT (which is basically a fair instruction of what one should do when encountering this toy in the aisle)! https://www.youtube.com/watch?v=FhGDkwrlsxQ

Ah! This one I remember. It’s like a fun ball and chain!

Comment 1, it does! But things look slightly less like devices of imprisonment and torture when they’re neon.
