There’s no one who doesn’t know how to use a straw, right??
Have you ever been embarrassed because you accidentally broke or burst a straw while inserting it? ㅎㅎ Now, try blocking the other side of the straw and inserting it. You will experience a new world where it opens in one go?
And if you’ve only been inserting the straw in the right direction so far, Now, if you insert it in the opposite direction, you can drink more comfortably. It’s usually hard to drink drinks that are on the floor.
But if you put it in the opposite way, the straw can reach the bottom, so you can easily slurp until the end ~~
