|Invented by||Hubert J. Farnsworth|
|Purpose of invention||To see through anything, including metal|
|First appearance||Fry & the Slurm Factory|
The F-Ray was an invention created by Professor Farnsworth. The F-Ray emitted a neutrino beam which allowed the ray's user to see through anything, including metal; because of this, it was even more powerful than the X-Ray. Its nuclear power was such that the Professor wore a full body radiation suit while using it. The Professor claims that it might even affect people over 10 feet away; although Fry has experienced direct exposure without any side effects, except the possible reduction of his sperm (he manages to impregnate his grandmother later in the series, after having much of his body repaired and retuned by worms he ingested). It is strong enough to pop balloons and blimps.
