LIQUID CRYSTAL COLOR CHANGE<br />
(3 of 5)<br />
Flashlight Beam Heats The Crystals Causing Change<br />
When exposed to differences in temp. between 77 deg.F & 90 deg.F cholesteric liquid crystals change color. They exhibit the flow and optical properties of a crystal in that they scatter light selectively.
