Question

when you blow on the other end of a brass instrument and hold a ping pong ball on where the mouth is suppose to be and blow. It will float in front of your mouthpiece until you run out of air.

how does it work?

why?

any websites or books?

How would this be use full in every day life?

Anyway to test to see with size mouthpiece would lift it the easiest? (like i was planing to use a air pressure machine but the air stream isn't constant)

also is there a cheap alternative instead of 50$ mouthpieces.
