Spring-Driven Boat Model
RIVER boats, with the paddle wheel at the stern, are well known in many localities. A simple little model, which will run fast, can be made as shown, from a board.
A, 18″ by 6″ by 1/2″ thick (although any size may be used) with a 3″ by 4″ notch cut in one end for the paddle wheel, and the other end tapered as shown.
The paddle wheel’, B, consists of two bent L shaped pieces of tin soldered to a 1/8″ metal shaft. The shaft is placed in screw eye bearings. To hold the front of the boat down the lead weight D, may be used.
Two stiff steel springs, C, with strings, E, attached to the free ends, are mounted on the board. The other ends of the strings are securely attached to the shaft. Wind up the wheel and the boat is ready to go.
MILLIONS for MOVIE IDEAS
By Frank Lloyd
THERE is upward of one million dollars waiting for you in Hollywood if you can find a satisfactory way of projecting motion pictures in three dimensions. There’s another million for some device which will create a universal focus for a camera. Possibly you could drive an even better bargain.
But before you start, remember that the best brains in the industry have been struggling with the ideas for years and nothing worth-while has been found. Hundreds of letters come to the studios, containing both shrewd suggestions and fantastic ideas, and still the search goes on. Scores of patents have been issued on both subjects and yet nothing good enough seems to have turned up.
Bridge Played Via Short Waves
CONDUCTING a bridge match in which the opponents were 6,000 miles away sounds incredible, but the Culbertsons engaged in just such a game. Using two official “dummies” who made the plays called for by the players located at Buenos Aires Mr. and Mrs. Culbertson engaged in the International Contract Bridge match although they were in New York.
At Buenos Aires an announcer named the plays made by the South American players. The “dummies” at New York followed these just as though they were opposing the Culbertsons, themselves. At the other end “dummies” representing the Culbertsons made the plays announced over the air.
New Power For Mechanical Toys Opens Large Field For Alert Inventive Minds
COUNTLESS inventors have rolled up tremendous fortunes by the development of new and simple toys as the several hundred manufacturers in this industry are ever in need of fresh attractions. Indeed, at the present time, there is an urgent cry for new material, and consequently we shall devote this month’s department to an outline of some of the more pressing problems. Toys can be developed by any man without an elaborate work shop since most of them are made of bits of wood and cardboard. Some of the biggest money makers on record have been perfected with little more than a jack knife.
FOR new Hallowe’en thrills, put on a mediumistic party with turban-bedecked medium, darkened room, spirit writing, tables floating in the air, and all the other tricks which fake spirit mediums use so successfully. The mere suggestion, on your invitations, that all weak-hearted persons should stay at home will insure a crowd.

ANT PALACES Create NEW Pastime
THOUGH it sounds like something out of “Alice in Wonderland,” the ant palace is a very real contrivance that sells for five dollars, and sells very rapidly at that. Strange things have been built in the name of entertainment, but seldom anything quite as novel and ingenious as these glazed-in ant apartments with both northern and southern exposure.
H. G. Wells Photographs the FUTURE in His Motion Picture “THINGS to COME”
SUBTERRANEAN cities flourishing under the scientific miracle of weather manufactured by machinesâ€”
Light-ray traps which recapture the very incidents of long vanished centuries so that you may watch Columbus discover America if you wishâ€”
Flowers and vegetables grown without soil or sunlightâ€”
Personal radio telephones carried on the clothing in a space no larger than a coat buttonâ€”
An electric Space Gun powerful enough to rocket human beings around the Moonâ€”
Boring machines which carry joy-riding passengers to Aladdin’s caves ten miles beneath the earthâ€”
These are some of the amazing achievements predicted for the world of tomorrow by H. G. Wells, world-famous British novelist who is hailed as the greatest prophetic genius of our day. With other miracles of the year 2054, they will soon be seen in Mr. Wells’ startling motion picture, prophetically entitled “Things to Come.”
Toy Train Delivers Rural Mail
“NECESSITY is the mother of invention.” An Oregon rancher, living a mile from the highway, proved the truth of this old maxim when he put the world’s smallest mail train in operation over a spur line between his home and the road to save his wife the trip.
The train, powered with small dry-cell batteries, makes the trip to the road every morning, pulling a tiny mail box. Upon arrival, it is stopped by a lever laid along the track.
Clock Wakes Sleeper with Music
THE violent hatred which humanity has for alarm clocks, especially around the hours of daybreak, may be mitigated somewhat by the invention of a combination phonograph and clock which awakens a sleeper with the strains of music from his favorite orchestra or singer.
Both phonograph and clock motor is contained in a box the size of a large camera, and the hour for the morning serenade is set by knob as in an alarm clock. When out of use the case is folded up to make a neat and attractive table or mantel ornament.
Birds Hit With Bullets of Light
BULLETS of light instead of the usual lead shot are being employed by Chicago’s sportsmen in a new trapshooting game.
The sport, which is said to be absolutely noiseless, may be played in an ordinary hall. It is held to be a valuable aid in perfecting marksmanship.
Photo-electric cells are mounted in the bodies of duck targets which move across a panelled opening at one end of the room. Each gun has its source of light which flashes on when the trigger is pressed.
If a marksman “hits” the photo-electric cell directly in the center of the bird’s body, the duck falls and the number of respective hits is registered automatically in light.
