Do you know what a small hole in a lollipop is working?

Eating lollipops all day but surely many people do not know the true use of small holes in candy sticks.

1. Why is there a small hole in the plastic seat, not another?
2. Why on iPhone headphones appear small holes?
3. Most aircraft have a small hole in the tail, but what effect do they have?

If you think, the hole in the candy stick works to prevent babies who suffocate if they accidentally swallow or blow a trumpet for fun after 'handling' the candy, then you guessed it wrong.

In the process of making candies, the stick is placed in the previous mold and then poured liquid candy. Meanwhile, liquid candy will flow into the slot and fill this hole first. Therefore, when the candy hardens, the candy in the small hole that acts to attach the candy clings to the stick like a nail, helping the candy on it not fall off the stick when packing or eating.

It's that simple, isn't it a big deal?
