Now with Boom Box Technology! Remote Controlled Fart Machine No.2 is the successor to the original, highly-successful fart machine. The new boom box feature adds more bass and volume to those booming fart sounds that you asked for. Armed with this device, you are guaranteed to embarrass your victims whenever the mood strikes you. Use it anywhere...at parties, school, movies, office, in a baby's diaper or in the Thanksgiving Turkey! Hide the sound box, then press the remote control at the appropriate time to "let it rip"! This new and improved model features fifteen louder sounds, works to up to 100 feet away and blows our original fart machine out of the park (so to speak)! As featured on the Howard Stern radio show, you know it's got to be funny! Operates on one 9 Volt (9V) battery not included.
