Adhesive Tape- home applience In 1923, inventor Richard Drew, watched as the painters at the Auto Body shop tried to paint the car with crisp dividing lines on two color paint jobs. Seeing this, Drew came up with the idea to create the world's first masking tape. In 1930, he made almost invisible ADHESIVE TAPE! It was made with oils, resins, and rubber with a coated backing. All this was possible because of 3M (Minnasota Minning and Manufactoring) who helped Drew's invention take off. We today call this marvelous invention SCOTCH TAPE! Tape Dispencer- home applience In 1932, John A. Borden created the first tape dispencer with a built-in cutter blade to cut the tape for you.  Ballpoint Pen- home applience ​Two Hungarian brothers, Lazlo and Georg Biro, came up with an invention that would help people all around the world. That invention would be the ballpoint pen. In the early 1930's, the brothers took the idea of a ballpoint from John J. Loud, who had created the orginal ballpoint pen in 1888. Loud's pen was wonderfully but it leaked and smeared when used to write on paper. By 1935, The brothers had put thier heads together and came up with a new ink to be put into the pens, which reduced leaking tremendously. Jet engine- Transportation Sir Frank Whittle from the UK constructed a jet engine in 1930. His engine could reach 466 mph and climbed to 42,000 feet. This proved to Bitish Air Ministry officials that a jet powered airplane was practicable.
