Why put a small ball in the toilet urinal

It's a stinky pill, and its smell can resist the smell of urine and can deodorize.

Stinky pills, also known as mothballs, are mainly composed of camphor, which can be sublimated (solid into gas) at room temperature, leaving no hawthorn, so it is widely used as a deodorant and moth-proof function. But it can't be sterilized.

Deodorizing!!

You see, as soon as the water rushes, the ball floats, and when it goes down, the ball stops the smell...

1. In order to let the boy concentrate on playing ball, he will not scatter casually.

2. In order to get rid of the smell!
