Our son shared a video of a car that got our
attention. In a matter of seconds the car went from
purple to red, blue, green, yellow and brown. It
was claimed that the paint changed colors
But according to Snopes the video was a phony
and the color changes were done digitally. The
funny thing is the paramagnetic paint is real and
has been in the works for years.
While the thought of changing your car’s color by
turning a knob sounds far fetched, Toyota, GM and
other car makers have been working on refining the
process for about 7 years.
It starts with a polymer coating with something
called magnetoheological dampers. Basically this
means the coating has paramagnetic iron oxide
particles in it.
When an electrical current is passed through the
coating these particles change alignment which
alters the way they reflect light and changes the
cars color. The default color, when no current is
running through the body, is white.
Got it. But this opened the door to so many more
questions our head started spinning. Would your
title state the color is white or would it simply
say “all”? What color would police cars be?
Would an officer in an unmarked squad car just
turn the knob to become a regular squad car?
Would criminals use this technology to evade
capture? You get the idea.
So take a look at the video and see what you think.
