19. #57 on the Heinz Ketchup bottle
Bottled Ketchup bottles look pretty and retro but they are actually a pain in the butt. Getting Ketchup out of this glass bottle is a difficult task…until now. The #57 is actually there to help you get your precious Ketchup. Put the bottle upside down, place it at a 45-degree angle and tap (hard) #57 for a generous flow of your favourite condiment.
