Liquid Crystal Sheet Demos10 thermal conductivity demos for less than $12 Watch Physics Teacher James Lincoln use the simple, inexpensive Liquid Crystal Sheet to visually demonstrate: -the temperatures of varying light sources -how styrofoam insulation works -the wavelength of a microwave -plus much more!
See Energy Transformation with a thermal camera or steel spheresCheck out how MLB can use a thermal energy camera to determine whether a hit ball is foul or live. Then watch Dr. Baseball use the more budget friendly colliding steel spheres to create some thermal energy of his own.
Doing the Wave: Connecting Physics to BaseballEver realized how waves and their properties are an integral part of baseball? See proof with this super slo-mo of a bat meeting a 90mph fastball!
The Blue-Violet Laser
The wavelength you've been missing!
Take a look at the new blue-violet Laser, which produces wavelengths at 405 nm. Sure, it is a different color and that is always cool, but why use this over any other Laser?
