Watch as it prints and try to figure out how it works.

Box contains a tube designed in such a way that it is noticeably easier to blow through the device one way than it is the other way.  

No moving parts.

Demonstrates Venturi effect.

No support material required even if slicer recommends.

By all means try and make a better version.
