"In a regular cube" proceeds to show you a cube that has a very advanced tensioning system. The regular tension system is just a screw without the blue ring that does your tensions for you.
I wasn't looking at the screen when this video started playing. I thought the sound of the boxes touching each other and him throwing it to the side was the sound of the cube turning, and I was like "HOLY CRAP WTF it sounds like clouds. I've never heard a cube that sounds like this" 😂
