Wow…I just found some old sketches for an app story about a crow that makes a submarine out of a two liter bottle. The story idea wasn’t great but I do enjoy the idea of a crow making a submarine.
Notice the rock ballast, the plastic spoon oars and the fork for picking stuff up. I have no idea how this thing was supposed to be water tight. Maybe the crow took a few classes on shipbuilding and hydrodynamics. It sounds very crow like to enroll in such classes.
