I bought FM2 for my 7 year old son and 3-year old daughter for Hanukkah this year. We installed the 9-volt battery and took turns operating the remote control while someone else pretended to be stricken with colossal gas. My wife couldn't stop laughing, and we quickly brought out the video camera to document the scene. FM2 will have you laughing your head (or should I say a--) off.Why, you may ask, did he rate this goofy toy 5-stars for educational value? Great question. The answer is it makes kids be creative planning and scheming the remote controlled fart, and in acting out the "farter" role.In all seriousness, FM2 is totally funny, and well made...and what can I say except kids love farts (and you will too).
