Vuvuzela Joke is not an ordinary vuvuzela!
The horn is activated with ambient noise!
Select the microphone sensitivity, put the iPhone/iPod on the table ... when Vuvuzela Joke detects screams, it emits the famous hum! (It is also activated by tapping on the screen).
But also ... if you put your iPhone/iPod with the screen facing downward, instead of hearing the sound of vuvuzela, you will hear the sound of a fart!
Use Vuvuzela Joke while you are watching the match with your friends. You will see many laughs when at some point you will hear the fart in place of the usual hum!
Note: Your iPhone/iPod must be placed from the desired side before it goes into standby.
The App is supported on all iPhone models, plus iPod 2G and higher models with an external microphone.
