Briefly: Like the harmonica, the slide whistle is one instrument you need no skill to play — you just blow in one end, and slide the other in and out. Unfortunately, that means that handing out a bunch of these adorable Wet My Whistle musical straws at your next get-together…

Turn a bendy straw into a shrimp with a pair of scissors and a few folds. The result is about as tasty as imitation crab meat. [InstructionsJP/InstructionsENG via Recylclart via Make]
