SWAMI (Apr, 1957)


As mystifying as the Indian rope trick, this magic marvel defies the laws of gravity.

PROBABLY Isaac Newton was right; but you couldn’t prove it with this gadget. It just seems to work contrary to all laws of gravity.

Swami, by itself, reacts like any other object: supported at one end only—it falls. But, add a fairly heavy belt, as shown in the photo, and it will not only stay up but actually take quite a bit of extra pressure to make it tilt down, even slightly.

We won’t tell you how or why it works. That is part of the mystery. Go ahead and make one and try to find out for yourself. You’ll be truly amazed.

Animate Your Photographs (Apr, 1953)

Animate Your Photographs

A pull on a string and this photo comes to life. To make this toy choose or make a photograph of your child (or even yourself) in a pose which shows the arms and legs suitably extended. Make two identical enlargements and glue these on thin Masonite or plywood.

Now you have two mounted prints; on one you will want to use only the torso, so mark off the legs and arms.

Easter-Egg Zoo (Apr, 1947)

Easter-Egg Zoo

BERTHE MARCHAND used her ingenuity. Needing something original for the Easter table—something for the children to admire—she hit on the idea of making an entire zoo of animals, using colored Easter eggs and other odd bits of material easily obtained for a few cents at any stationer’s.

Why don’t you do the same? It just takes patience, nimble fingers, and extreme care in handling the eggs— which can be dropped only once.
(Maybe you’d better boil them.)

“Poor Man’s” Yacht (Apr, 1957)

“Poor Man’s” Yacht

This floating dream-home will allow you to cruise the river in millionaire style.

By Rudy Arnold

HAVE YOU ever dreamed of cruising down the river in your own private yacht? If you have, now is the time to do it and enjoy the plushness of a modern dream-home complete with front and back yard.

Wesley H. Dyer’s “Dumbo” has made a low-cost family yacht a practical reality for the water-loving landlubber. Dyer, president of the Metal Products Company of Nashville, Tenn., named his original family yacht, shown on these pages, after Walt Disney’s flying elephant because his novel craft was big but surprisingly agile for its size.

Interesting Experiments with Air Currents (Jul, 1930)

Interesting Experiments with Air Currents

by C. FRANCIS JENKINS – Famous Inventor

You’ve seen flags flutter in the breeze, watched airplanes fly, read of buildings which collapsed from the inside out in tornadoes—but do you understand the cause of these phenomena? Mr. Jenkins, famous for his inventions in the field of television and inventor of the movie projector, has devised a number of fascinating experiments to test the behavior of air currents. Try them for yourself, as explained below, and you’ll have a better knowledge of why airplanes fly and why gliders glide.

“ICE LIZARD” (Feb, 1940)


by L. B. Robbins

AIR minded, ice-boat and mechanically-inclined fans: here is something to arouse your imagination and ingenuity—an air propelled ice-boat using a washing-machine engine for power and capable of good speed and breath-taking thrills. Let’s build a fleet of these “Ice Lizards” for the height of the skating season and give the populace something to talk about.


Wow, this is actually the second guy I’ve seen with homemade stainless steel dentures. Here is another from 1937. I wonder how common this was.

STEELY SMILE of John Gilpin, village blacksmith of Livingston, Mont., is really friendly although strangers are sometimes awed by it. Gilpin broke a set of store teeth 16 years ago, replaced them with rugged stainless steel.

Build A Glider-Copter (Aug, 1954)

Build A Glider-Copter

AN 86-lb. helicopter glider, believed to be the smallest aircraft in the world today, has been developed and flown by Bensen Aircraft Corporation of Raleigh, N. C, for use in engineering tests of lighter-than-man helicopters.

Like soaring gliders and sailplanes, the helicopter glider has no engine; it is towed by a car until it becomes airborne and will stay in the air as long as it is towed or as long as there is sufficient wind to keep its rotor blades turning.

Simple Electromagnet Does Mystifying Stunt (May, 1932)

Simple Electromagnet Does Mystifying Stunt

THE well-known barrel of monkeys could produce no more entertainment than an electromagnetic “circus,” consisting of a powerful solenoid magnet and a number of accessories, that you can construct in an evening.

And besides being a source of fun. such a device is highly instructive, and will serve to clear up many of the mysteries of everyday electricity for you.

The electromagnet or solenoid consists of nothing more than a quantity of insulated wire wound on a spool, and provided with a suitable base, connecting wire and plug.

HOW TO TAP A PHONE (Mar, 1957)


By Tony Karp

THERE are many ways to tap a phone; most of them against the law. Our little gadget, however, is quite legal and can be used to great advantage at home or in the office.

Basically, the unit consists of a pickup coil, an amplifier and a speaker. The pickup coil is placed under, or near, any transformer-type telephone without being in physical contact with it. As the electrical currents pass through the phone, part of the energy is induced into the pickup coil.
