Antigravity Craft, Lifters, Books

This page shows our anti-gravity lifters and related power supplies and other materials necessary to build and actually fly these amazing devices. This unit when properly constructed has always been a winning science fair project. It was also assembled and demonstrated on MythBusters. We show a beginning approach starting off with a smaller unit and then working into larger units. For those really interested in pursuing this technology we offer larger power supplies and other support to assist the researcher.

Special note from our technical staff

This project demonstrates a very important and interesting -- but not well known -- property of electrical energy. This phenomenon of direct electrical reactions produces a thrust, generating the effect of "anti gravity". With this property it is possible to cause direct motion, movement, and positive lift, making it viable candidate for ion propulsion of hovercrafts, hoverboards, space travel and the like. It has already proven itself in outer space as a high-efficiency thruster.

This project includes an Ion Driver that can generate over 1ma at 20kv. This Ion Driver requires a power supply (not included) of 12V and at least 3A, such as a 12V battery or wall adapter -- you can use your own, or we can provide one if needed.

You build the craft that then levitates without any visible means (you must provide the simple materials for this craft, such as foil, glue, wire, and balsa wood from a hobby shop). The triangular shaped craft is typically built 6" to a side, or you can make a larger craft up to 14" when you get your first one correctly flying.

This project has been an award-winning science project for many years. It is very popular in high school grades 8 to 12, College, museums, and even has been featured on TV, one show being MythBusters who built the kit.

A CD-ROM is included that contains valuable information on assembly and flying hints of many sized and shaped craft that require simple construction and use readily-available low-cost materials.

The GRA1/8 Ion Drivers (shown below) are duty cycle pulsed sources of high voltage. Both produce the same 20,000 volts necessary to generate the ion flow, but the GRA80 has an enclosure and voltmeter for those who want to take more analytical measurements of performance.

Project Requirements:
1) The Ion Driver (a GRA80 or GRA10, as sold here)
2) A Power source (not included; must be 12-14V and at least 3A)
3) A Craft (not included; made by you from lightweight materials; instructions on how to make these craft are included)

The builder has a choice of two Ion Drivers:
gra80 The GRA80 Ion Driver is the Deluxe Version with a volt meter, fuse, and comes enclosed in a plastic case. Leads are strain relieved with a special anti corona plastic tube for connection to the high voltage output. All else is the same as the GRA10. Includes CD with pictures, video, instructions, and other information.

- Assembled Deluxe Ion Driver ... $159.95
- Kit & Plans of Deluxe Ion Driver ... $129.95
gra80 The GRA10 Ion Driver is the Low Cost Version, built on an open frame. It is a less-fancy version without the enclosure, meter, or fuse, but has the same functionality and power for a lower price. All else is the same as the GRA80. Includes CD with pictures, video, instructions, and other information.
- Assembled Low Cost Ion Driver ... $129.95
- Kit & Plans of Low Cost Ion Driver ... $79.95

The GRA1/8 combination plans are also available by themselves, and contain instructions for assembling both the GRA10 and GRA80 Ion Drivers (plans are included with the assembled and kit versions):

Ion Emitter Wire For AntiGravity Lifters

This thin 2-mil stainless steel wire is the best we've found to reduce lossy corona and provide maximum thrust and lift, but it may be hard to locate, so we provide it for you here if you don't have access to it locally. Very strong for its diameter. You can try other types of wire, such as thin copper filament, but we have found that they just don't have the electrical or weight characteristics to work efficiently. Ten feet of this wire is enough to build 2 or 3 smaller craft with 6"-14" sides, and 25 feet of wire is available for those wanting to experiment with larger antigravity craft designs.

- 10 Feet Stainless Wire ... $15.00
- 25 Feet Stainless Wire ... $25.00

Attention -- For Those Wanting to Build &
Experiment with Larger Crafts up to 4 feet:


The HVOLT50V(+) is a 50KV 5ma power supply capable of driving larger craft up to 48" in size, click here for details.

Electro-Magnetic Pulsed Rocket Launcher

Winning Action Science Project


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 metallic 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).
