13. Play Doh
Many people have fond childhood memories of playing with Play Doh and it’s all thanks to Noah McVicker. In the 1930’s the family soap company decided to try and make wallpaper cleaner and started developing different concoctions. The substance was created out of water, flour, salt, boric acid, and mineral oil and it was meant to capture all the dirt off wallpaper without sticking to it and leaving a substance. The dough worked decently for wallpaper but was more entertaining than anything. The stuff you see in stores today has the addition of food coloring to make play time even more fun.
