There’s a reason bungee jumping uses a bungee cord. It’s because they’re elastic. That applies to every sort of bungee cord, even the ones you use to tie something to your car or wrap around a box.
This Reddit user admits their big mistake when they pulled on one end of the bungee cord while the other end was stuck on something inside the trunk. It looks like it smacked them right in the face. It’s a surprise they still have both of their eyes (via Reddit).
