near-frictionless yo-yo bearings, 2 hour spin time

And we will still be preoccupied by which yo-yos spin the longest. I can picture it now:
“Well that one only spun for an average of 135 minutes during my trial… not nearly as good as my daily throw which spun for 145 minutes averaged between 10 throws…”

My thought is that the string rubbing against the response is what limits current spin times. If there were a way to eliminate or dramatically reduce that, it would result in a huge jump forward.

Stringless yoyos that you play with by creating and manipulating small magnetic fields.

Bearings that spin my magnetic forces= no friction

Not true for a strong centering bearing though, the string basically never touches the edges, at least not on a throw to sleep!

Yeah, that’s fair.

Agreed. I’m referring to improving spin times during play. That would be a welcome advancement. I almost think a particular technique combined with a new design could accomplish this, much like the bind ushered in unresponsive play.

Yes, we can hope for contaminant free lettuce in the future. After that all is well in the world.

Well in that case maybe I’ll pray for non-GMO corn and soy beans in the future?

Yay! non GMO all the way!
A grooved centering magnetic bearing. Inner race and outer race oppose each other and float. Zero friction.
Edit: Should have kept reading. @Marm already mentioned this.

I read it, but I was saying It’d be magnetic
