Make this ball Bounce!

An app for everyone! You just have to launch the ball in order to make the ball bounce (on the edges of your phone) as many time as possible within 10 seconds and try to beat your record. Your result depends on how strong you launched the ball to bounce but also where you launched the ball to bounce. Try to find the better way to launch the ball to make the best score possible!
