Rubber
The Native Americans were the first to create rubber. We’re led to believe the Europeans created this invention when it came from elsewhere. Originally, the Native Americans collected latex from rubber trees and combined it with sap and morning glory vines until it hardened into rubber. They did this over a fire. The process was a long and arduous one, but worth the result. Because the Europeans had better trading networks and infrastructure than the Native Americans, they appropriated a lot of their inventions. Colombus took a rubber ball, from the Native Americans, back to Europe, where it gained in popularity (Discover Magazine).
