"Dutch researchers believe they have cracked the physics behind a mysterious bouncing behaviour of liquids, first seen more than 40 years ago.
British engineer Arthur Kaye first noticed this weird phenomenon in 1963, while experimenting with a mixture of obscure organic liquids. When he poured his viscous mixture on to a surface, the down-going stream would suddenly throw up a jet that merged with the incoming stream." read more...
Amazing, though I still don't reallt understand it.
ReplyDeleteAlso a beautiful video clip!
What I understand is that shear thinning(viscosity decrease with rate of shear stress) causes a large decrease in viscosity, which creates a smooth(due to low viscosity) ramp that guides the stream back into the air without much friction.
ReplyDeleteThis looks spectacular! Remarkable how that stream bounces up.
