"Positive Expiratory Pressure" device - you can also accomplish this using a straw, pinching it slightly so you have to force the air out as you blow.

Pinching the end? Or the part in your mouth?

I taped the end of a straw almost completely shut, but you can get the same effect from just holding your lips real close as if you're trying to blow out a candle. The tighter the better, as long as air is still getting through, and you're pushing against it with your lungs.
