Comical Mouse Circus Brings in a Steady Income
Troupe of little mice cavorting about in this freak circus displayed in merchant’s windows will attract huge crowds of passers-by—and net one a neat profit.
HERE is a money-making idea that is worth at least five hundred dollars of any man’s money. It is a veritable gold mine for any man who has even the tiniest spark of mechanical ingenuity—and it has been thoroughly tested and proven as a cash-getter.
It’s a mouse circus, using trained mice which aren’t trained!
Its usefulness is in creating a window attraction for stores in all lines of business. Two days’ trial on merit will convince any of ‘em.
Its cost is slightly over two dollars per circus, and each circus rents for a minimum of three dollars per week to merchants. Upkeep is practically nil.

If my dad had really loved me, he would have built me one of these.
Boy Won’t Need Dad’s Car Now!
Thirteen-year-old Jimmy Richardson of Tucson, Ariz., is the envy of all his friends with a midget auto built by his father. What’s more, he rides all week on 56 cents worth of gas — the cost for one tankful. The car is made of 20-gauge steel trimmed in stainless steel for a snappy appearance. It stands 2-1/2 feet high, is five feet long and has a ground clearance of only five inches. Built on a frame of bed rail with knee action in front and regular coil springs in the rear, the entire machine weighs about 300 pounds.

A Diving Helmet from a Water Heater
THEY go down to the sea in old water heaters along the Atlantic coast these days, now that some young man with a leaning toward aquatic sports has proved how easy it is to make an excellent diving helmet from a metal water heater which will enable its wearer to walk comfortably on the sea floor 35 feet and more below the surface. A few feet of garden hose, two pairs of bellows, a couple of valve boxes and a cylindrical metal boiler of the type used in most homes for heating water, are the essentials for building one of these helmets.

BASEMENT Golf
By Allan Carpenter
POPULARITY of miniature golf has brought the game right into the basement in the form of a knockdown course that can be picked up and stored away almost as easily as you would a game of croquet. It’s an exciting game the whole family can enjoy the year round—from the youngsters on up to the avid golfer who will find it good practice in keeping his putting eye keen. Standard putters and irons are used and scoring is done as in real golf, penalties being counted as strokes. As for space, most basements, especially those with compact heating units, will accommodate the “concentrated” nine-hole course pictured in the illustration above, but, where there’s only a minimum of space, a lot of fun can be had from a much smaller course. As each green is complete in itself and lightweight, the course can be quickly set up. Most of the greens are fairly shallow to permit stacking them in little space when not in use. Where yard area is sufficient to permit an outdoor course, a suggested layout for an 18-hole one is given in the plan view on page 197. Construction of nine additional greens is given to supplement the nine shown above.

A Fan Motor Television Receiver for Experimenters
by L. B. ROBBINS
Here is a simple and easily-built type of television receiver with which you can pick up the television images now being transmitted over the air from a number of stations.
THE time is now ripe for radio fans who build their own sets to construct a television receiver. Several broadcasting stations are on the air transmitting on both long and short waves, and have so perfected their apparatus that a simple receiver like that illustrated in the accompanying drawings will bring out the pictures with a fair degree of clarity and brilliancy.

I’m not quite sure why this poor kid has to put the candle on his head to prove some “scientific” point. It looks like it’s about to set his hair on fire.
Novel Dry-Ice Gun Extinguishes Candle
To within 1/4″ of the edge, cut out the top of a cardboard salt box, and tie a piece of rubber balloon over it. Cut a 1-1/2″ hole in the opposite end, roughening its rim with a penknife. Load the gun with carbon dioxide gas by inserting “dry ice.” Aim the gun, tap the rubber, and an invisible ring of gas will smother a candle flame six to eight feet away. You can stage an amazing “William Tell” stunt with the gun as shown below.

PLYWOOD PLAY PLANKS
Give your child countless hours of interesting, instructive, and clean play by making him this jumbo-size set of building blocks.
ANY kid who has this plank set will be . the hero of the block—and his hero will be his dad for making it for him. With the set, he is equipped to build any number of walk-in projects. Houses, forts, ships, castles, garages, locomotives—there’s no limit to the designs that healthy imagination and young hands can produce.
The planks are light and clean. They are simple enough for a three-year-old to use, yet interesting enough to keep a ten-year-old busy. No nails or fasteners are needed —the planks interlock strongly and safely. They won’t crack or warp and children can’t break them. Even the most ambitious play-plank buildings can be dismantled and stored in a few minutes.
