Yes, I’d be happy to! Let’s try some experimenting. What do you think is the best way to do this?

I thought blowing air out through the teeth in some particular way. Also the placement of the tongue and the shape of the lips might have some influence on the sound it makes.

I think you’re right, that is what I’d try. What do you think of the following techniques?  You can also try any techniques you want, that you think could work.

But you didn't tell me what you know.
