History of the duct tape goes back to 1945, during World War II there was a need for waterproof, strong cloth-based tape that could keep moisture out of the ammunition cases. Johnson & Johnson invented in 1945. Ever since then, it’s become common knowledge that you can fix everything with duct tape.
Within the TheEndApp, duct tape is the currency. You collect it while running, and then spend it to buy goodies for your camp. You should buy stuff that ensures your survival, like a brandy distiller, a dog kennel, dumbbells, and of course, a hammock. Your camp can be upgraded to a luxury camp, but you gotta be a great runner to achieve that.
Duct tape has a long history in media. Cult TV series such as MacGyver, Beavis and Butthead, Two and a Half men, and Mythbusters have featured Duct Tape. Not to mention big-budget movies like Apollo 13.
