Cardboard Box Upright Bass

Borrowing from the typical "washtub bass" construction method, this guy built an upright bass from a cardboard box.

If you've got a hardwood plank (he used a piece of scrap flooring), a weed whacker cord or similar, and a couple of faucet spigots laying around the house, you can build an upright bass yourself!

Is it playable? You be the judge. Sounds good to me.
