Delivering pizza can be an unrewarding and sometimes dangerous job, and you never know what you’re going to find when you show up to someone’s house with their pie.
Bad case scenario- the person opens the door and robs the delivery guy at gunpoint. Best case scenario- you show up at inventor Ivan Owen's house and your footsteps are greeted by sweet music!
Ivan and his darling daughter built "musical stairs", installing pressure plates connected into pipe organs, then they called the pizza delivery guy and watched the fun unfold one step at a time!
