ADHESIVE TAPE
Richard G. Drew (1899-1980) invented masking tape and clear adhesive tape (also called cellophane tape or Scotch tape). Drew was an engineer for the 3M company (the Minnesota Mining and Manufacturing).
Drew’s first tape invention was a masking tape made for painters in 1923 (this tape was designed to help painters paint a straight border between two colors). This early masking tape was a wide paper tape with adhesive on only the edges of the tape – not in the middle. Drew made an improved tape called Scotch (TM) Brand Cellulose Tape in 1930. This tape was a clear, all-purpose adhesive tape that was soon adopted worldwide. The first tape dispenser with a built-in cutting edge was invented in 1932 by John A. Borden, another 3M employee.
AIRPLANE
The first working airplane was invented, designed, made, and flown by the Wright brothers, Wilbur Wright (1867-1912) and Orville Wright (1871-1948). Their “Wright Flyer” was a fabric-covered biplane with a wooden frame. The power to the two propellers was supplied by a 12-horsepower water-cooled engine. On December 17, 1903, the “Flyer” flew for 12 seconds and for a distance of 120 feet (37 m). The flight took place at Kitty Hawk, North Carolina, USA.
