Artificial Flower

Silk and other artificial flowers manufactured today are breathtakingly real and must be touched if they are to be distinguished from nature's own. Silk trees bring the outdoors into sterile offices, and flower arrangements change the color and feel of a room for a relatively small investment.

Bean Bag Plush Toy

Investors who worry about bull and bear markets should consider the alternatives—the moose, lobster, pink pig, platypus, and dolphin markets, just for starters.

Bioceramics

Over the last several decades, bioceramics have helped improve the quality of life for millions of people. These specially designed materials—polycrystalline aluminum oxide, hydroxyapatite (a mineral of calcium phosphate that is also the major component of vertebrate bone), partially stabilized zirconium oxide, bioactive glass or glass-ceramics, and polyethylene-hydroxyapatite composites—have been successfully used for the repair, reconstruction, and replacement of diseased or damaged parts of the body, especially bone.

Crash Test Dummy

Like a fashion mannequin, the dummy looks like a human, but its more-than-skin-deep beauties consist of high-tech instrumentation and a state-of-the-art physique. And like the ventriloquist's version, the crash test dummy can't speak except in a highly effective series of television commercials for seat belt safety.

The unfertilized egg is considered an important and inexpensive food source, particularly high in protein, including 0.21 oz (6 g) of complete protein per two-ounce egg. However, it also includes 0.42 oz (12 g) fat, both saturated and unsaturated, which is nearly all located in the yolk.

Electric Automobile

Unlike the gas-powered automobile, the electric automobile did not easily develop into a viable means of transportation. In the early twentieth century, the electric car was vigorously pursued by researchers; however the easily mass-produced gasoline-powered automobile squelched interest in the project.

An envelope is a flat, flexible container, made of paper or similar material, that has a single opening and a flap that can be sealed over the opening. The envelope is usually sealed by wetting an area of the flap.

Fishing Lure

The way to a fish's stomach is through his eyeballs, and fishing lures are objects that resemble any of the naturally occurring foods that fish might find attractive. The purpose of the lure is to use movement, color, and vibration to grab the fish's attention and cause him to bite the hook.

Fishing Rod

A fishing rod is a device used in sport fishing that consists of a long pole with a line held in place alongside it with the use of guides. Usually the line is kept in storage on a reel that the angler spins to both take up and let out the line while casting.

The name for galoshes originated in the Middle Ages when many styles of boots from short to long were popular. The word came from Gaulish shoes or gallicae, which had leather uppers and soles carved of wood; when the Romans conquered the territory they called Gaul (France), they borrowed the Gaulish boot style.

Glass Ornament

When Christmas trees were still a new custom, inventive methods of decorating trees with as much light as possible were developed. Actual lights, from candles to electric bulbs, were used, of course; but, to magnify the sparkle and fascinate the young, metallic tinsel and glass baubles became accessories for the well-dressed Christmas tree.

Glue

It is estimated that about 40 lb (18.2 kg) per year of glue are used for every person in America, and it is easy to see how and why when one looks at the extent of uses. Furniture, plumbing, shoes, books, buildings, and automobiles all use glue in some part of their construction.

Scientists describe the mousetrap as a device that is "irreducibly complex." The mousetrap cannot be made more simply and still function, and, at the same time, it is so simple and does its job so well that it gives the illusion of being a profound achievement. "To build a better mousetrap" means to achieve an ideal, to reach a pinnacle of achievement, or to create the best possible device in an imperfect world.

Paintbrush

A paintbrush is a handheld tool used to apply paint or sealers to paintable surfaces. The brush picks up paint with filament, includes a ferrule that is a metal band that holds the filament and handle together and gives the brush strength, a spacer plug within the ferrule which helps the filament sits tightly in the brush and creates a reservoir for paint, epoxy to lock the filament, and a handle which provides comfort and good balance.

Parachute

A parachute is a device used to slow the movement of a person or object as it falls or moves through the air.

Silly Putty

In 1943, Silly Putty was accidentally invented by James Wright, an engineer in General Electric's New Haven laboratory, which was under a government contract to create an inexpensive substitute for synthetic rubber for the war effort. By combining boric acid with silicone oil, a material resulted that would stretch and bounce farther than rubber, even at extreme temperatures.

Sword

The development of the sword was not possible until ancient civilizations discovered how to mine and work metal. Thus, the first swords were probably made of the oldest worked metal, pure copper.

Telephone

Throughout history, people have devised methods for communicating over long distances. The earliest methods involved crude systems such as drum beating or smoke signaling.

Thread

Thread is a tightly twisted strand of two or more plys of yarn that are circular when cut in cross section. It is used for hand sewing and in home sewing machines.
