Tuning the viscosity of a "smart" fluid using light

Tuning the viscosity of a "smart" fluid using light.
Research of Aimee Ketner and Rakesh Kumar.

Is it possible to switch a fluid from a thick jelly state to a thin water-like solution by shining light? And moreover, is it possible to do make such a fluid using simple, cheap chemicals? We show that this can be done in our our JACS (2007) paper, where the "recipe" for the fluid depicted in this movie is given. The movie shows our photoresponsive fluid that is initially very viscous, but becomes very thin and pourable upon UV irradiation.

@skyhawk431 i get it but wtf

@mancool124 That's the point. It's called hypocritical humour. Learn to take a joke.

@skyhawk431 "learn TO grammer" ?????? wtf Learn how to spell!

@adahqkrazutopiax Learn to grammer

It can switch back again?

[adahqkrazutopiax]

u really r stupid. its a breakthrough found by people with brain n published in a very good journal. u can stick to or own experiment n the only breakthrough it will be is deeper to ur own brainless brain

WOW amazing

How can I buy this fluid? or How can prepare it?

[Alexc3217]

its the uv light

[Alexc3217]

you dont understand anything do you? One its the light that does this NOT heat, two, the uses of a smart fluid can be implied into a machine to control lubrication (grow up), machines heat up so it wouldn't work, also YOU DONT USE JELLO IN A MACHINE!!!

have you seen the color at that fluid?

i mean when it's expose to light.....
