Folding Cane for the Blind
Blind persons can now obtain a white cane that is folded when not in use. The lightweight cane is made of aluminum tubing coated with white plastic. When the cane is held by the wrist cord and allowed to fall freely, the four aluminum segments snap together and become a rigid unit. Rubber tubing inside the cane draws each segment of the metal tubing into the next larger diameter to a depth of one inch.

HOME EXPERIMENTS WITH HYDROGEN
by VERNON TRACEY
HYDROGEN, the lightest of chemical elements forms a very interesting field of experiment for the home chemist. It can be produced easily in several ways for experimental purposes; one of the most common of which consists of the action of sulphuric acid on zinc.
A flask into which is dropped a few grams of zinc scraps is fitted with a rubber stopper, thistle-tube and delivery-tube as shown in the photo. The thistle-tube is fitted into the stopper so the end will be about 1/8″ from the bottom of the flask. The end of the delivery-tube is near the top of the flask. Dilute sulphuric acid is poured down the thistle-funnel and hydrogen is produced when it comes in contact with the zinc. The top of the thistle-funnel is covered with a piece of glass to prevent the hydrogen from escaping. The hydrogen flows out through the delivery-tube and is collected in a bottle over the pneumatic trough.

HOW SCIENCE SPEEDS THE COUNTING OF 40,000,000 VOTESHUMMING over wires from every corner of the nation, election returns in a few days will bring the answer to the question of America’s 40,000,000 voters: Who’s elected ?
Years ago, many days would pass before positive results of a Presidential election were known. Today it is a matter of hours and minutes. To make this possible, a scientific network of communication machines—teletypes, telephones, telegraph, and radio—manned by an army of workers, has been recruited and promises the earliest election returns in history. But nothing will aid the vote gatherers more than the voting machines that this year number 35,000 in twenty-two states.
First used around the turn of the century, the voting machine, by reason of its speed, accuracy, and honesty, has come up in popularity until this year it will tabulate nearly a third of the votes cast.
So you may see how modern high-speed machines count the votes, Popular Science selected a typical Mr. and Mrs. America and, in the series of pictures that follows, starts you around the clock with them on Election Day and shows you how they may well know on the same night “who’s elected!”

Aquaplane Towed by Auto Outrigger in New Water Sport
WATER enthusiasts are now able to skip along Pacific waves without actually going to sea. A 20-foot pole attached by a swivel to the rear end of an automoible does the trick. The aquaplane rider skims over water two feet deep as the car speeds 20 miles along the beach. The pole is fastened by a bolt attached to a rear bumper and can be swung over when the car is turned around.
One brace rope swung from the top of the spare tire or the handle of the door fitting over the rumble seat holds the pole horizontal while a forward brace rope, swinging back from the radiator cap, holds the pole against the backward pull. The weight of the entire additional equipment, including pole and rope, is only 34 pounds.
