The app literally makes your iPhone or iPad blow out air that can extinguish candles or blow away paper or tiny bits of things. Turn your volume all the way up and their app produces sound waves that spit out air and blows away things. Check out the video demonstration below:
I have tested this out on my iPad 2 and works. Some people claim it doesn't work on their iPad 1. This does not work on the iPod touch. At $0.99 this app makes an excellent conversation piece and is worthy of its novelty. Check it out on the appstore.
