Radiometers: three “light mills” from my growing collection of radiometers (now at 28 so far), including a double with two spinning flys in the same partial vacuum volume. Here the initial light is from a LED, and then a halogen incandescent bulb is turned on which activates the motion. This device goes way back, invented in 1873 by the famous chemist Sir William Crookes when he was investigating partial vacuum environments. Light heats up the “vanes” which then heat up the very thin gas left in

Santa Radiometer: a St. Nick themed classic physics toy- a light powered ornament for a tree near a sunny window. This device goes way back, invented in 1873 by the famous chemist Sir William Crookes when he was investigating partial vacuum environments. Light heats up the “vanes” which then heat up the very thin gas left in the partial vacuum within the bulb- the black side of the vane is hotter than its reverse and any gas molecule that comes into contact with it flies off at a faster speed im

Double Radiometer: a rare version of this classic physics toy with two rotators enclosed in the same partial vacuum chamber. Light heats up the vanes which then heat up the very thin gas left in the bulb- the black side of the vane is hotter and any gas molecules that comes into contact with the black fly off at a faster speed imparting impulse to the rotor. The bottom rotor has black on the right side of each vane and rotates clockwise, the top rotor has black on the left sides and thus has the

IR Laser Pointer: here’s a strange find- a laser pointer that emits a beam in the infrared wavelength of 810 nm, which is invisible to human vision. We can see the effect of the IR beam on a radiometer as compared to an equal low wattage green laser beam of 532 nm. The IR beam seems to heat up the panel more effectively. What is the use of an invisible laser pointer? My guess is that it may have some use when wearing night vision goggles. Since IR is invisible, great care should be taken with th
