An Instrument that you breathe inwards?

Hey guys, i know this may not be the right location, but i just have a quick question.

Does anyone know if there is any instrument that you breathe inwards to make a sound? I cant think of any haha.

Thanks

Some harmonicas have two reeds which operate depending on the direction of the wind. I.e., one reed for blowing out and one reed for sucking in.

Wow pretty cool. Any other instruments?

You can make cool sounds on the bassoon and oboe by sucking at the attached mouthpiece. That's not really the normal way of playing them though :P

Other harmonica-like instruments work similarly of course, such as accordeons, in which the air also flows in two directions, producing different results, but that's not really "breathing", since you do that with your hands.

Also, the most obvious instrument that you always carry with yourself - your mouth. You can whistle while breathing in. It could be harder for some people in the beginning, but it's cool and works great, because, combined with breathing out, allows you to not interrupt your whistling for long periods of time. :P
