Scientists Crack The Physics Of Coffee Rings :
Scientists now know why coffee rings have dark, well-defined edges, as seen in the image above. The research finding may have implications on the development of inks and paints.
Well at least we have our scientific priorities in order! Now they can focus on the important stuff, like investigating the crystallization of dust bunnies, the physics of headphone cord knots, and the gravitational science behind the levitating door frame arms trick.
BAHAHAHAHAHAHAHAHA!!!
This is one of the things I like most about watercolour. If they go and change the way paint is made I don’t know what...
I want to know what those developments are.
