ChemDemos is a video laserdisc that includes 33 demonstrations suitable for use in introductory chemistry classes either at the high school or college level. The emphasis is on the chemistry, with most demos shown close up, full screen.

Most of the video is now included in the Chemistry Comes Alive! Collection.
