Where to put it after absorption

The starting point is very good, but as a not very old yan gun, generally y will not spit down... One is the problem of habit, and the other is that the taste of Y is actually very difficult to remove, which will make the clothes stained with a heavy taste of Y, and then the whole person will have the taste of Y, will it be more embarrassing, uh, just provide some personal opinions...

Where is the motor...

Interesting idea, is there such technology now?
