The Smell-O-Scope was an invention created by Professor Hubert J. Farnsworth. It allowed users to smell odors over extremely long distances. Though it was damaged in Bender's Big Score, it later returned, intact, in The Beast with a Billion Backs. Another, smaller version, shaped like a large cake, was also featured in The Beast with a Billion Backs.
Based on true world technology.
