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.

Includes everything you'll need to show that electricity can act very much like a magnet. One large nail, one five-foot piece and one 1 1/4-foot piece of plastic insulated wire with end connectors, one knife-edge switch, two screws, one 3" x 4" x 1" wooden block and complete instructions. Battery not included.
An efficient and easy way to demonstrate Faraday's Law and Lenz's Law. To show and teach how a magnet when passed thru the complete loop causes the loop to move and when passed thru the cut loop causes no movement. 6"H x 7"W. 2.25" Diameter loops.
Experiment with magnetism, create fun games, and amaze your friends. Magically dangle a chain of marbles from the wand, make the marbles dance without touching them, and more. Includes 1 magnet wand (7.63 inches long) in assorted solid colors and 5 bicolor magnet marbles (.63 inches in diameter). Ceramic magnets are completely encased in plastic. Ceramic magnets are the most lightweight and economical magnets. Children safety tested for ages 4+.
