FM-3613 'whityel Bay' Smoke CellDemonstrates the 'Brownian Moon' or random moon of smoke particles. A specially designed plastic box has a sliding lid at the top and contains a glass smoke cell, a cylindrical condensing lens, and a low voltage festoon bulb. All components pre-adjusted so as to focus the light of the festoon bulb to the sm..

FM-3376 Air Compression Fire GeneratorThis device is used to illustrate that pressure and temperature are related. When you press down quickly on the plunger, the air is compressed inside the tube, igniting a cotton ball. The fire then instantly goes out, because all of the oxygen in the tube is exhausted. Can be used to illustrate the kindl..

FM-3603 Air Pressure CupsA striking demonstration of the famous 17th century experiment with this simple, modern a variant of the old equipment to illustrate without a vacuum pump, the enormous force of air pressure. Two near-hemispherical rubber cups, when held together face to face and squeezed to force out the entrapped air, it becomes sur..
