Whitley Bay Smoke Cell Kit – Demonstrates Brownian Motion

The Whitney Bay Smoke Cell Kit is an ingenious device for visualizing Brownian Motion in gases. A molded plastic box is fitted with a cylindrical perspex condensing lens, an LED bulb, and a smoke cell. A 12V DC power supply (not included) is plugged into the lead terminals on the box. Smoke is introduced into the system via a squeeze bottle and delivery tube attached to an inlet on the box. Brownian movement resulting from the random impact of molecules is observed through a compound microscope (not included). Includes instructions. Size of chamber: 4″L x 2.7″W x 1″H.
