I once was stranded on a rural highway after a freeway-closing accident with only a can of tuna to eat (and a pair of chopsticks). Luckily, I had a multi-tool with a can opener. Had I only had a spoon, then this somewhat obscure hack would have come in handy. I won’t even go into how odd I looked eating tuna from a can using chopsticks, all while stuck in a completely stationary traffic jam. Since you never know when you might find yourself without a can opener, this hack on how to open a can with a spoon could, theoretically, come in handy for someone.
