Color Me Excited, Seeing spectra in a whole new light [W/Video]
Teaching the spectra of visible light can be an engaging classroom activity. But, it’s always been challenging to find ways to go beyond simple passive demonstrations.
Hand-held diffraction “rainbow” foil (sometimes mounted in cardboard glasses) can be fun. But students often have difficulty even spotting the spectrum. “I can’t see it!” is the common complaint. And [...]
SpillNot: The Physics Behind the Slosh [W/Video]Although the problem of why coffee spills might seem trivial, it actually brings together a variety of fundamental scientific issues. These include fluid mechanics, the stability of fluid surfaces, and interactions between fluids and structures (we’ll set aside the biology of walking for now). The SpillNot is a cool tool for getting your students interested in the everyday physics behind why drinks spill while we’re carrying them and what has to happen to prevent spillage.
Top 10 Demonstrations with the Plasma Globe [W/Video]What can you do with a plasma ball? We get this question a lot! Check out these simple, cool demos using everyday lab items like fluorescent lamps, LEDs, neon gas tubes, and even your own body! You’ll be amazed at how easy and fun teaching and learning about electrostatics can be.
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?
