Wait is this a Coca-Cola ad?! Where are the polar bears?
Building A Floating Tensegrity Chair Large And Strong Enough To Support A Person

This is a video of Youtuber The Q building a chair based on tensegrity (aka floating structural compression, links to Wikipedia) that’s large and strong enough to support the weight of a relatively lightweight adult human and a Coca-Cola can. Now I read the Wikipedia article I linked to above about tensegrity, and now I’m looking at this chair here, but I still can’t wrap my head around it. My penis? At least once with more to spare, easy.
