Lightning in Your Hand (Oct, 1946)

Lightning in Your Hand


By Loren W. Gay

NUCLEAR physics, the unpredictable baby of the sciences, is about 50 years old. For the first two thirds of its short life it crawled patiently along on all fours. Then, without bothering to walk, it started to run. Just where it’s running to, no one knows, but it has already revolutionized man’s conception of his universe without even stopping for breath.

How to Put a Ship in a Bottle (Aug, 1930)

How to Put a Ship in a Bottle

Making a full-rigged model that folds so as to enter the neck


“HOW did it get there?” is the question always asked when a ship model in a bottle such as shown in Figs. 2 and 3 is placed on exhibition. You will observe the curious minded examining the bottom of the bottle to see where it was cut to admit the ship, or they will even inquire if the bottle was blown around the ship. But there is no fake about it; everything goes through the neck. With patience and determination, anyone can make this curious and always mystifying type of model.

Universal Cable Adapter (Feb, 1960)

Universal Cable Adapter

By Art Trauffer

Built into a typewriter ribbon case, this adapter permits over 50 combinations of cable connections.

WHEN the writer finished making this adapter he started to count the different combinations of connections that can be made with it, but when he reached 50 he gave up. Certainly, 50 is not the limit for this versatile and easily-made adapter. If you build one of these you will save much time and trouble when joining together various types of connectors in radio and electronics experimental and test work.

Car Touch-Up Sprayer for 25c (Nov, 1952)

Car Touch-Up Sprayer for 25c

BEFORE you buy an expensive spray gun and compressor, try an artist’s fixative atomizer, available for 10c to 25c at art and drafting supply stores, model shops, and at many hobby and craft shops. Used by artists and architects to spray their pencil and chalk drawings with fixative to prevent rubbing, this gadget can perform many small painting jobs, using only lung power.




THIS doorway harp will produce a merry melody at the front entrance to your home every time someone enters or leaves. One friend remarked that it should serve as an excellent deterrent to salesmen, since its sounds would distract them long enough for you to shut the door!- Be that as it may, the harp never fails to prompt a “Who’s playing the guitar?” from visitors, and is a good ice-breaker when welcoming guests.

This Novel Martin House Is Built to Resemble Zeppelin

Edited by A. NEELY HALL

BIRDS ought to appreciate this latest design in apartment houses, built to resemble a Zeppelin. To make it, secure nine pieces of one-inch white pine and saw them into 10-sided partitions as shown in the drawing below, the middle partition being 12-1/2 inches in diameter and the others tapering down to 6 inches.

“Bombs Away!” (Nov, 1952)

“Bombs Away!”

THIS lively game will give you all the thrills of knocking the daylights out of an enemy city with well-placed “demolition bombs” without the least danger to the bombardier, although the area below is bristling with antiaircraft guns.

The bomber (Figs. 3 and 4) slides on a revolving arm supported by a central post (Fig. 2) and is moved by hand until it is over target selected. By looking through the bombsight with its cross-wires the airman can get a direct line on target and release marble “bomb” by a hand lever.

Fun with an Old Spark Coil (Jan, 1932)

Fun with an Old Spark Coil


ALTHOUGH producing a spark only about three-eighths of an inch in length, an auto (Ford) spark coil can be made to produce a brilliant stream of sparks, about two inches in length, by interposing small flakes of graphite throughout the gap. This is easily accomplished by dusting flake graphite on a tacky varnish card through which are fitted two machine bolts or binding posts for contact with the secondary terminals.

Mechanical Flying GOOSE Decorates Radiator Cap (Sep, 1931)

Mechanical Flying GOOSE Decorates Radiator Cap

For novelty in radiator ornaments, you’ll have to go a long way to beat this mechanical flying goose. As you speed along in your car, an ingenious arrangement of mechanism in the bird causes it to straighten out and flap its wings to simulate a real live goose in flight.

WHILE your car is standing still this wild goose isn’t so wild. He perches sedately upon the radiator cap surveying the world with a glassy eye. But as soon as you start up and shift into high he flattens out his tail, stretches his neck forward and begins to flap his wings as if he were going somewhere, and going there in a hurry.
