Say hello to the new and improved fart machine! Why do we only sell the Fart Machine #2 and not #1? Well, let's just say it is so good, no one remembers its predecessor exists anymore.The Fart Machine #2 makes 15 new different fart sounds using boom box technology to make them louder and more realistic. It comes with 2 separate pieces, a remote transmitter, which has a range of up to 100 feet and even works through walls, and a speaker. The separate pieces let you use the Fart Machine #2 anywhere -- at parties, in school, at the movies, in the office, anything you can think of, because then, you can just hide the sound box, then press the remote control at the appropriate time to let it rip! And yes, the sound box even comes with sticky pads so you can hide it under chairs and tables.The Fart Machine #2 is not suitable for children under 3 years due to small parts. The remote contains an included battery, and the speaker requires a 9V battery (not included).
