25 lenses including ACHROMATS, double convex positive, concave negative lens, WWII infra-red bomb site lens, miniscus, eye pieces, etc. These lenses, if purchased at todays prices, would cost well over $500.00! All pieces individually available in quantities.
Electro-Magnetic Pulsed Rocket Launcher
Winning Action Science Project showing the interaction of pulsed magnetics and high moment of acceleration of an actual small rocket. A demonstration quickly stimulates classroom interest.
Our rocket project will capture the attention of both young and old. Safe for the classroom and powered by 12 volts (includes wall adapter), it easily propels the model rocket beyond most classroom ceilings. This is a great classroom participation project stimulating the students to design a vehicle that achieves maximum range as a result of their own ingenuity. You build the rocket body around the motor ring from balsa wood, tooth picks or other common light weight materials. The rocket motor is nothing more than a small light weight aluminum ring. Range of the motor by itself is easily over 100 feet. The launcher section contains the circuitry and all controls to power up the system. To operate you press and hold the CHARGE button and count down until the READY LIGHT comes on, press the FIRE BUTTON and watch it fly.
Device uses LENZ'S LAW to generate the force for propulsion. This force is produced when a conductive non-magnetic ring such as a 1 turn aluminum ring (MOTOR) is closely coupled to another coil usually of more turns. When a fast changing current is applied to the multi turned coil, it creates its own changing magnetic field now inducing a very large current in the 1 turn ring coil. This current now creates its own magnetic field that opposes that created in the multi-turn coil. This impulse of opposing magnetic fields now produces a powerful short lived repulsive force providing kinetic energy to the motor ring.
White "charging" push button charges up the energy storage capacitors.
Indicating neon lamp comes on indicating proper amount of charge is on the capacitors.
Red "fire" push button triggers the launch.
Front panel 2.1 mm dc jack for 12 volt input (wall adapter included).
Coil Gun Pistol
Danger: will cause injury or break objects at close range. Point in a safe direction and treat as a firearm! Caution -- Adult Supervision Required!
Fascinating project propels aluminum rings to a considerable velocity. Demonstrates the LORENTZ force plus important properties of magnetic energy. Rings may be restrained to flyway for safety or classroom demonstration. Adult supervision usually not required for outside use. Operates from 8AA batteries that slide into hand grip. Can be easily modified to propel ball bearings.

The Amazing Magic Man
Great effect where a person can walk into a darkened area, bring his hand near a fluorescent or neon lamp, and cause it to glow. The user can pick up a tube by the glass envelope causing it to eerily glow as if the user is radiating energy. Under some conditions he may cause the effect just going near it!
The assembled MAGICMAN is built into a 6 x 1-1/2" cylindrical enclosure, battery operated, easily worn, and ready to be used by the wearer.
This product is one of the neatest and coolest items when used for getting attention at a bar or party. You can cause your friends to become electrified. When they touch a glass beer mug it will mysteriously glow, even a small fluorescent bulb. You can actually electrify a second party, sometimes even a third if the conditions are right, and the third-party just by holding onto the second party can actually cause a neon tube to light up. Experimentation is suggested to be able to optimize the capability of the device. Truly an amazing product.
The bizarre high tech phenomenon allows the wearer to light household fluorescent lamp simply by holding in hand. It is even possible to ignite matches, gas burners, grills, etc. Neat concept opens up many exciting ideas and variations to keep your friends (or audience) amazed!
This product when used with any glass neon artifact can provide a lot of magical entertainment. A similar item sold by Spencer Gifts, plasma mug patent number US05270619, is owned by the originator of Information Unlimited Inc.
The Amazing Electric Man
You charge yourself to a voltage that gives annoying electrical shocks by direct touch, or transfers an electric charge by proximity. Go to a party and move about, mingling with people unobtrusively. Many will unknowingly become charged by proximity, receiving annoying shocks as they later touch each other or metallic objects. A real nuisance but a great gag. Make fine powdery material jump to your hand as if by magic. Touch the rubber bumper of an automobile where fresh dry snow will fly off, as if by magic. Walk into a dark area where there are fluorescent light bulbs, and they will flash dimly.
If the user has any latent telekinetic ability (or wants to make it look that way) this will be greatly enhanced. Make a strip of paper, place on the end of a pencil, position in a block of clay. Find a wooden table, stare at paper, concentrate and cause it to move, proving your ability to cause this motion by mental concentration. This is a great party function, when mastered will amaze those present.
The assembled ElectricMan is built into a 8 x 1-½" cylindrical device with batteries, easily worn and ready to be used. A choice of two power supplies are offered to customize the system.
Great party gag, prank, magic trick or special science project, using 30kv high voltage with a very low current for a safe and effective spark or transfer of electricity.
Amaze people when they see actual sparks jumping from your fingers to various objects and igniting torches, grills, gas stoves, etc. In a dark room, bring your hand near a fluorescent light-bulb while still in the socket and watch the flash as your hand is brought closer.
Make paper stick to walls, attract powder, sand, dry snow to your hand showing the power of the electric force fields.
Several users have claimed enhanced telekinetic powers. They set up a pencil stuck in a piece of clay in an upright position. The sharp point is used as a bearing for a folded piece of paper about 1 inch in width and maybe 8 inches long and balanced as a rotor the pencil point. This assembly is placed on a wooden desk and you sit at it covertly placing your foot on a conducting surface as a metal plate or tray under the desk. You now cause the rotor to rotate with the slightest movement of your hand or even nodding of your head. This is one of the most amazing demonstrations of apparent telekinetic properties and can be elaborated on to produce a real attention getting paranormal feat!
A lower voltage unit is demonstrated on YouTube with one of our -20kV power supplies (SS-010SD1-1) for this project. A -30kV higher voltage unit is also available (SS-015SD30N). Both of these operate from 12 vdc.
Makes a great party gag, prank, magic trick or special science project.
Dynamo Generator AC/DC
To generate AC (alternating current) and or DC (direct current). On turning the wheel current starts to generate, on flipping the switch to ac or dc the corresponding bulb lights up. Open construction and all the parts are easily visible.
