To study Spectral Lines of Pure Elements / Gases. Gas under pressure in the tubes is used to produce a light for spectral analysis. Brightness of light depends on the nature of gas. Optimum intensity, line resolution and longer life. Metal ends with long life electrodes. About 26 cm long, with 90 -100 mm of central capillary. For intermittent use only, not to be used as a lamp source. These are designed to operate 30 seconds ON~30 seconds OFF. Need Spectrum Tube Power Supply or an Induction Coil, sold separately.

This kit is great for all doubting Thomases in your elementary through high school classes. Fast, fascinating and easy. This kit includes: Two black-colored blocks with rim for holding melting ice cube in place. The "cooler" one is of aluminum, which is an excellent conductor of heat. The ?warmer" block is of plastic foam, which is a very poor conductor of heat.

Turn your students into human gyroscopes with our wide, stable rotating platform. Now you can do the "skater's spin" without skates, a rink or ice! Our 16" (40cm) wide bright blue wooden disc has a nonslip surface and safely holds over 220 pounds (100 kg). Intended for hands-on (or feet-on) use, the unit has very low friction when supporting a weight of 100 pounds. Instructions describe experiments in rolling friction and gyroscopic precession with sample questions. Features include non-skid decals on surface for safety, and bright blue 16" diameter wood discs.
