NATIONAL ZIPPER DAYNational Zipper Day commemorates April 29, 1913, when the patent for the modern zipper was issued. The day celebrates something that we often do not think about and may automatically take for granted.The first attempt at creating the zipper came from the inventor of the sewing machine. In 1851, Elias Howe received a patent for the “Automatic, Continuous Clothing Closure.” However, Howe never marketed his invention and missed the recognition he may have received. Anyhow maybe it's a small element but very necessary in everyday life .For more information you may go on Google and find something about it .For enjoy the day you may sew the clothes or any article
