ways to open them.
Currently, almost all soda cans use the same type of opener, one that has a separate piece of metal attached to the can at a single spot which can rotate 360-degrees around. The metal-piece is used to depress the wide-mouth top into the can. But is that all? Can the metal-piece do something else?
Yes! It's designed to assist you in another way, but sadly few realize this.
The little hole in the metal-piece is intended to make it easy for you to use a straw. You swing the piece around so it's over the wide-mouth and then stick your straw through it. It will hold the straw in place. Otherwise, if you just put the straw into the wide-mouth opening, it will bounce around and not stay put.
Boy, you're so smart now!
