Safely create and explore lightning, right in your classroom These popular Plasma items give you a safe, fascinating way to demonstrate how lightning works as well as an explanation of the concepts of potential differences and electron orbital jumping. A small Tesla coil produces a large potential difference between it and the surrounding glass, similar to a cloud and its potential difference with the ground. A small Tesla coil generates a large potential difference to simulate lightning. Students see how light is produced from charged gases. Plasma Mug This potential difference uses inert gases inside the globe to complete a circuit and release its potential to the outer glass, just as a cloud releases its potential to the ground. The result? Bright, harmless, violet “lightning bolts” that respond to touch and sound. For more information and power requirements for each item, visit www.arborsci.com. P2-7110 P2-7115 7" Globe Plasma Mug $49 $27.95 P2-7105 P2-7113 3" Mini Globe $19.95 Lumin Disk (6 in.) $29.95 If lightning strikes, where do you want to be? A great accessory to our Van de Graff generator or other electromagnetic sources. The Faraday Cage named after Michael Faraday is an enclosure designed to exclude electromagnetic fields. Our cage is made of sturdy, finished steel and comes with plastic insulator cups, aluminum conductor cups and a mounted conduction point. Diameter 12 cm and height 26 cm. A great companion to our P6-3370 Faraday Cage $21 Hand-held Tesla Coil (below)! Lumin Disk’s display responds to touch, voice, or music! Powered by 110 V (adapter included) or batteries (you supply). Compare the Van de Graaff generator with the Wimshurst machine and let students discover the difference between current and voltage. Lumin Disk visit arborsci.com for: > FREE Downloadable Product Demos! > Secure Credit Card and P.O. Ordering! > Real Time UPS Shipping Quotes! …and much more! Momentary on/off safety switch Hand Held Tesla Coil If you’ve seen a Plasma Globe, you’ve seen a Tesla Coil in action. As exciting as our Van de Graaff Generator! Insulated base prevents charge from traveling to other objects. Invented by Nicola Tesla, this high-frequency transformer can step up ordinary 110-volt electricity to thousands of volts. Create impressive 3-inch sparks or use the high potential to light bulbs such as our spectrum tubes (p. 7) or Neon Wand (above), without touching! Adjustable from 10,000 to 50,000 volts, with momentary on/off switch in the bakelite handle for improved safety. P6-3550 Hand Held Tesla Coil $185 Produce a higher current with lower voltage! Produce static electric charges and discharges with our Wimshurst Machine. Use the hand crank to rotate the plates in opposite directions. The close proximity of the plates will produce a substantial charge which is then deposited and stored in the Leyden Jar capacitors. Your students can create a high voltage, yet modest, and therefore safe, current source. Mounted on insulated base. P6-3350 Wimshurst Machine $89 For more shocking demo ideas, browse the CoolStuff archives at www.arborsci.com Hold the Tesla Coil near our Neon Wand (above) for a dramatic demonstration of electric potential.
