Daily Riddle, Oct 20, 2026

The trick here is that your brain hears "put into" and immediately pictures adding something, which should logically make a barrel heavier, not lighter. That's the misdirection doing its quiet work. A hole flips the whole idea of addition on its head: to create one, you're actually taking material away, not putting anything in. So the barrel loses wood, metal, or whatever it's made of, and that loss is what makes it lighter. The riddle also leans on the fact that a hole is purely an absence — it has no mass, no visible form, nothing you could hold up and point to. It only exists in relation to what surrounds it. That's why "cannot be seen" and "weighs nothing" fit so naturally once you stop thinking of it as a thing and start thinking of it as a missing thing.
