Chupa Chups
This well-known lollipop brand has a uniquely-shaped hole at the top of each stick, but people don’t seem to know why that is. It turns out that the square hole is there to help the lollipop stay firmly on the stick while it’s being made.
Heinz
At their best-selling moment, Heinz had 57 different kinds of food that they were offering. Today, the number 57 is placed on each bottle to indicate the best spot to hit the bottom and get the ketchup to pour out. It’s very handy when you’re struggling to get that last little bit of ketchup out.
