Now you can easily perform Lord Kelvin’s famous electrostatics experiment right in your classroom. -- This large demonstration apparatus includes a water reservoir with tubing, droppers, brass rings, wire, two “catch cans,” and a lamp, all mounted on a 53 cm (H) x 25 cm (W) x 6 cm (D) wood base. -- As the water flows through the droppers and rings and into the catch cans, the droplets break apart, inducing an electrical current. The current travels up the wires to light a neon lamp placed at the juncture of the wires. -- As the water continues to flow, the lamp flashes, corresponding with the negative resistance characteristics of the neon. -- This demonstrator is easy to set up and comes with everything you need, including instructions and explanatory notes.
