First Flying Hoverboard

The Hiller VZ-1 Pawnee (above) was basically a unique direct-lift rotor aircraft, using contra-rotating ducted fans for lift inside a platform upon which the single pilot shifted body weight for directional control. The platform, touted as the world's first flying hoverboard, was developed starting in 1953 under an Office of Naval Research (ONR) contract to Hiller Aircraft Corporation, and flew successfully, starting in 1955. Due to aerodynamic effects in the duct within which the propellers rotated, the platform was dynamically stable, even though the pilot and center of gravity of the platform were fairly high up. In testing, the prototypes flew well, but the U.S. Army judged them to be impractical as combat vehicles as they were small, limited in speed and only barely flew out of the ground cushion effect.

Orbitz Drink

Orbitz, the lava lamp-inspired food creation, was a noncarbonated fruit-flavored beverage, made by the company Clearly Canadian Beverage Corporation, that had small edible balls floating in it. It was introduced around 1997 and quickly disappeared due to poor sales. The small balls floated due to their nearly equal density to the surrounding liquid, and remained suspended with assistance from an ingredient known as gellan gum. The gellan gum provided a support matrix - something like a microscopic spider web - and had a visual clarity approaching that of water, which increased with the addition of sugar.

Play-Doh

The non-toxic, non-staining, reusable modeling compound that came to be known as "Play-Doh" was originally a pliable, putty-like substance concocted by Noah McVicker of Cincinnati-based soap manufacturer Kutol Products; it was devised at the request of Krogers Grocery, which wanted a product that could clean coal residue from wallpaper. Following World War II, with the transition from coal-based home heating to natural gas and the resulting decrease in internal soot, and the introduction of washable vinyl-based wallpaper, the market for wallpaper cleaning putty decreased substantially. McVicker's nephew, Joe McVicker, joined Kutol with the remit to save the company from bankruptcy; he subsequently discovered that the wallpaper cleaner was being used by nursery school children to make Christmas ornaments.

BlackBerry Phone Knockoff

Most techies know that Barack Obama has been using a BlackBerry for years, but it may finally be about to call time on his relationship with his beloved BlackBerry for an Android smartphone.

Disposable Camera

Disposable, also known as single-use cameras, were pretty big back in the 80s and 90s, but the kids of today are probably more accustomed to snapping shots with their smartphone to post on social networks. On a similar note, did you know that a company called Photo-Pac produced a cardboard camera beginning in 1949 which shot 8 exposures and which was mailed-in for processing? That's right, cameras were expensive, and would often have been left safely at home when lovely scenes presented themselves. Frustrated with missing photo opportunities, H. M. Stiles had invented a way to enclose 35mm film in an inexpensive enclosure without the expensive precision film transport mechanism. It cost $1.29. Though incredibly similar to the familiar single-use cameras today, Photo-Pac failed to make a permanent impression on the market. Continue reading for more.
