This Material Remains a Liquid 200 Degrees Below Its Expected Freezing Point
And it changes colors when it's touched.
Researchers at the University of Michigan have created the neatest piece of goo since Nickelodeon created gak.
The new "supercool" material stays liquid when its temperature drops more than 200 degrees Fahrenheit below the expected freezing point. What's crazier is that the color changed from dark red to yellow when it was lightly touched.
Jinsang Kim, a co-author of the study, described it as a "domino effect" in a university-issued release because the touch forced the molecules to crystallize. When the liquid was at room temperature, "the thicker supercooled liquid crystallized only where the stylus made contact" allowing them to actually write notes on it.
Besides looking cool, the material was developed for real-life applications like in electronics because they are cheaper and more flexible than silicon.
