And was created superglue. During the Vietnam war, the us military used superglue to arrest bleeding in open wounds. Thus an invention which was to improve the weapons saved many lives.

3. Stickers Adhesive used on stickers, invented by an American physicist Spencer silver,while they themselves are self-adhesive post-it notes were invented by Arthur fry pastor. In 1968, silver was working on creating the perfect glue for paper-handling: it (the glue) should hold the paper on the surface, but not much, and so to be able to remove the paper without tearing it, and it had to be suitable for repeated use. However, the company where he worked silver anyone the idea is not interested in his idea.Pastor Arthur fry proposed to use the substance to create reusable sticky tabs and he began to use the glue to stick the bookmarks in the hymnal.

8.Stainless steel. English Metallurgist Harry Brearley was trying to create the perfect alloy for the production of weapons — light, durable, does not corrode. Stainless steel came when he mixed with 12.8% chromium 0.24 % carbon. Turned out the alloy, which was looking for Brearley. This alloy was stable even to acids of vinegar and lemon juice.Much later the inventor realized that the resulting alloy is ideal for Cutlery:they were made of silver and carbon steel and quickly fell into disrepair due to corrosion.
