I was reading your post and I briefly thought you were trying to say it IS expensive, not that it is not. And I was like is this guy on crack, cubing is cheap as chips.
Anywho, glad to see I was wrong. I learned cubing at the same time as my buddies kids did, and while I never got faster than I think a minute and a half? They are well under a minute now, it’s crazy.
I still cube occasionally, but mostly just to fidget while watching TV 🤷♂️ Also so I don’t forget how to do it.
It’s actually because of wind resistance, the air is moving the same speed as the ground when the earth turns so you don’t feel it.
(don’t @ me I’m just following what I recognized to be a humorous pattern of technically correct "well actually"s)
