Everytime I fart, I am very thankful that fart has no colors!
So I thoight, what if there is a jeans that makes me look I fart, but in fact, I don't. So when I really fart,
I won't be embarrassed.
The fart is painted by a special ink, when the temapture gets higher, the ink will change its color.
For people who wear this jeans, if they sit long enough, the fart will appear.
