iBlow is a test of how long you can continuously blow out. To play just blow into the microphone of your iPhone (or external mic for iPod Touch users) and a ping pong ball will rise in the tube on the screen. It is just like a lung capacity test except with a game built in. Try to beat your high score by keeping the ball from touching the top and bottom for the greatest number of seconds. Your high score will be saved even when you exit the app. See which one of your friends can keep the ping pong ball up the longest with this fun, addicting, and exciting app.
Sometimes it is just a test of who feels light headed first!
