Armchair World's Grating Spectroscope Kit
Make your own spectroscope! What is a spectroscope you ask? It's an optical device that breaks light into a spectrum. Spectroscopes have many uses: scientists use spectroscopes to study the chemical composition of stars, metallurgists use spectroscopes to determine the composition of mineral specimens, and chemists use spectroscopes to determine the constituents of chemical compounds. Our spectroscope kit is made of thick, silver-colored cover stock and comes with a pre-cut slit and a pre-mounted diffraction grating embossed with 23,000 lines per inch. To assemble the spectroscope, simply cut it out, fold it up, glue it together and you're ready to observe the visible spectrum. With the Armchair World Spectroscope you can view continuous, bright line and absorption spectra including Fraunhofer lines in the solar spectrum. The Kit comes with an instruction sheet detailing several simple investigations you can make using light sources in your environment. Educational, useful and a great stimulus for expanding your knowledge of the world.

We are manufacturers of the Grating Spectroscope Kit. If you are a museum store or school, contact Armchair World at products@armchair.com for quantity prices.

How to Order
Posi-Dry(tm) Printing Out Paper
Bring out the artist and the scientist in you. Posi-Dry enables you to print dark blue silhouette images of transparent, translucent or opaque objects on a white background. Posi-Dry is a unique dry process system. Simply lay your objects on the Posi-Dry light sensitive paper and expose to sunlight or a light bulb until the yellow paper turns white; then iron the paper for about five seconds; this turns the yellow image into a dark blue permanent image. In the 1920's and 1930's, photographic artists used photo darkroom techniques to make Photograms. Now, you can do it without a darkroom and chemicals. The Posi-Dry(tm) Kit comes with a foil envelope with 20 light sensitive papers, a clear plastic envelope with 20 ironing papers and an instruction sheet. A great initiation to photo sensitization and photo printing. Fun and educational for ages 4 and up.

Product Code: S-115$5.50 ea.
