Father and Daughter Team Build Air-Powered ‘Musical Stairs’ and Surprise a Pizza Delivery Man

Musical Stairs Pizza Delivery

Inventor Ivan Owen and his daughter built air-powered “musical stairs” using pressure plates and antique organ pipes. After their build was complete, the pair ordered a pizza to see how the delivery man would react to the sound.

Owen has created a number of interesting inventions in the past like a steak knife weed-whacker, a cornstarch flamethrower, and his daughter helped him build an electric cereal-eating machine.
