Antigravity Lifter You Build and Fly


laser pointers

This page contains our anti-gravity craft power supplies, and other materials necessary to build and fly these amazing devices. When properly constructed, these devices have always been winning science fair projects. Our anti-gravity craft was also assembled and demonstrated on Myth-Busters (Season 4, Episode 26).

We recommend first building a smaller craft, before building larger units. Our base model anti-gravity power supply can power craft up to 3 feet per side, and for those really interested in pursuing this technology, we offer larger power supplies and other support to assist in your research.

Special note from our technical staff

Anti Gravity Hovering Craft and Lifters
This project demonstrates a very important and interesting, but not well known, property of electrical energy. It is now possible to cause direct motion, movement and positive lift making it a viable candidate for vertical propulsion, hovercrafts, hoverboards and future space travel.

This item has been an award-winning science project for decades. It is very popular in middle school, high school, College, museums, and even has been featured on TV, one show being MythBusters (Season 4, Episode 26) who built our kit in 2006 and filmed it hovering and levitating.

Units use duty cycle pulsed sources of safe high voltage at a low current. The resulting phenomenon of this specific electrical reaction produces a thrust with an audible “throbbing sound”. This thrust is what makes your craft levitate and fly generating the effect of "anti-gravity". It has already proven itself in outer space as a highly-efficient thruster, where it is used as a propulsion method for satellites and deep-space probes. As stated so many times, “Today’s experimental research will be tomorrow’s reality."

Experiment in the Science of Levitation

Here are some examples of different-sized
anti-gravity craft that can be built and flown:

6” craft shown in detailed assembly instructions, and parts for assembly included in all purchases
Plans GRA1GRA8
47 Pages In Color

12” craft built using same technique as 6” craft. Easily powered by our GRA1GRA8
and included

3 ft craft built using similar technique as smaller versions. Easily powered by our GRA10/HV350CC/HVPSD50KV(+)

A larger 6-8 ft craft can be built using similar techniques and a little ingenuity. Easily powered by our HVPSD50KV(+)

And these are the power supplies
that provide energy to fly these craft:

GRA10: the lowest cost power supply, and preferred by hobbyists, experimenters and for science projects and classroom functions. Has the same power output as the more-expensive HV350CC.


HV350CC+: with a protective enclosure, this power supply is preferred for use in museums or public and special displays. Fully enclosed with panel meter for monitoring craft voltage, and with all plugs and jacks for plug & play operation.


HVPSD50KV: For serious experimenters who want to attempt a 6-8 ft/side craft, for a total area of 18-32 square feet!

This power supply has enough energy to fly a properly made craft over 6 ft per side, demonstrating amazing lifting forces greater than a kilogram. Output is adjustable from 5 to 50 kv (delivers 6ma regulated at 50kv).


To make and fly an anti-gravity craft, just purchase one of our power supplies, and then build a 6" craft (you must provide the simple materials for this craft, such as foil, glue, and balsa wood from a hobby shop. Our power supplies include emitter wire, and our instructions show how to make the craft from all these materials). Your first triangular shaped craft is typically built 6" to a side, and you can make a larger craft up to 14" once you get your first correctly flying. It is very important that the craft is built exactly as shown in the plans for best performance.

GRA1/8 - Paper Plans ... $25.00
GRA1/8-D - Downloadable Plans ... $15.00

The GRA plans contain instructions for assembling both versions of the power supplies (the GRA10 and HV350CC). These plans are included with the assembled and kit versions and do not need to be purchased separately, but are available here if you want just the plans. 47 pages of full color.

Please note instructions and plans are combined into one document and  can be credited to purchases of either kit or assembled units

WIRE2MIL10 - 10 Feet Stainless Wire ... $15.00
WIRE2MIL25 - 25 Feet Stainless Wire ... $25.00
MULTI50 Voltage Multiplier Module ... $49.95
The 10' of stainless emitter wire is included with each power supply, but is also sold here separately if you want to build more, or larger, anti-gravity crafts.

The MULTI50 is a voltage multiplier module which can be connected to a 10-15kvac flyback power supply, increasing the output voltage by 5x. Recommended only for those who already have a flyback transformer.
