In specially coated tubes, the more viscous a liquid is, the faster it flows
It's widely known that thick, viscous liquids—like honey—flow more slowly than low-viscosity liquids, like water. Researchers were surprised to find this behavior flipped on its head when the liquids flow through chemically coated capillaries. In fact, through these specially coated tubes, liquids a thousand times more viscous flow ten times faster.

Typically, when someone presents a demonstration of "Doom running on X," it's a way to demonstrate how powerful low-end computing has become.

This tendency also results in Doom being played on devices that aren't a lot of fun to play with (which is integral to this story). This story i
