Observe:
The paper ketchup cup we all know and put up with. Everyone recognizes it. Everyone has squeezed its contents onto their burgers at some point in their life.
But this mild mannered, everyday paper cup was designed to be so much more! Each of those paper ridges is supposed to be unfolded and when they are......
BAM!!!
Plate of ketchup! Now dipping onion rings is a breeze, why you could even dip your hamburger in it if you really wanted to.
Apparently this knowledge was advertised when the cups were first released, but soon the ads stopped, and so the knowledge was lost to a generation of people, but the design was never changed.
Spread the word my friends! The ketchup revolution starts with you. Free your friends and family from the chains of fast food ignorance!!
(Was that a bit too melodramatic? I can never tell.)
