Have you ever wondered why the can of your favorite drink has a small hole in the opener? Probably not. It is not a decoration, it has a special task.
American engineer Ermal C. Fraze is responsible for the cans we drink from today. In 1963, he patented his idea for opening cans.
The hole in the opener serves as a straw holder, making it easier to drink liquids. It is better to drink juice from a can with the help of a straw than to put your lips to it.
The drinking opening on a can can be very dirty, full of bacteria and viruses, who knows where it was until it got to you.
See how easy it is to insert a straw into the opening.
What's more, the first straws were made from reeds a long time ago, more than 6,000 years ago.
