Watering cans or pails can be made from the 2-gal. cans in which motor oil is frequently sold. Remove the top with a can opener and add a bail of heavy wire that has been slipped through a hole in a piece of broomstick. The holes in the can through which the bail passes must be reenforced by soldering on washers. A length of discarded tubing may be used as the spout, and the handle that was originally on top of the can is removed and soldered to the back.
Punch a few holes near the bottom of a can, to represent the ash-pit draft, and attach a tin tube for a chimney. With a candle for a fire, you have a heating plant in miniature, which can be observed through a window tightly covered with a piece of mica. Obstruct the draft holes or chimney, and the "checked" flame burns dimly. A fan breeze over the chimney opening increases the draft and brightens the flame, as does a "forced draft" produced by pointing the fan at the lower holes. Deflecting a breeze from the chimney, reduces its effect
Take an old tin can, and from it cut a small propeller, each blade of which is about 21/2 to 3 inches long. Bend the left edge of one blade down a little, and the right edge of the other one up a little.
With a small nail or brad, put a hole in the exact center of the propeller, and firmly insert a thumb tack through it to the end of a small round stick about 1/4 of an inch thick.
To fly the "Wingless Wonder," twirl the stick rapidly between your hands, quickly push it up over your head, and let go. The fast-whirling propeller will carry it up into the air quite a distance.
Children's Stilts Made from Two Tin Cans
Perhaps the simplest type of stilts possible to make are those fashioned from two ordinary tin cans. The cans should be of the one- or two-quart variety.
First see that one of the ends of each can is neatly cut off. Turning them upside down - that is, with the open end on the ground -punch two holes on opposite sides of each can, about an inch from the top, or closed, end. Through the holes run a strong cord or twine sufficient to comfortably reach your hands when you stand up on the cans.
By lifting the string and can with each step as you walk, you'll have a simple little pair of stilts-and you can't fall off and hurt yourself, either.
