The Exploding Toilet episode was the first of the Mythbusters series, after the pilots.


  • Can a person be propelled off a toilet seat by dropping a lit cigarette into a toilet bowl when filled with various combustible materials?
  • Is running better than walking to keep dry in the rain?
  • Is it possible to make a "magic bullet" out of ice?



1) An assassin can fire an ice bullet to kill someone without leaving a trace.

BUSTED - The bullet was simply too brittle to be used.

(This myth was revisited in episode 14 and it was busted again.)[1]

2) An assassin can use a meat bullet to kill someone without leaving a trace.

BUSTED - The meat bullet fragmented on contact with the skin, causing only superficial damage.[1]

3) An assassin can use a gelatin bullet to kill someone without leaving a trace.

BUSTED - The bullet did not cause fatal injury.[1]

4) An assassin can use a poison capsule fired from an umbrella to kill someone without leaving a trace.

PARTLY CONFIRMED* - It was found to have been the cause of death for a notable Bulgarian dignitary, Georgi Markov. The catch is that the umbrella must be fired from point-blank range for it to work.

  • It was confirmed that the event is possible, but not that it’s untraceable.[1]


Pouring gasoline down a toilet and lighting it will cause the toilet to explode.

BUSTED - The gasoline simply burned without exploding. Not even a tin of gunpowder in the toilet bowl was able to eject Buster from the seat.[1][N 1]


You stay drier running in the rain than walking.

CONFIRMED* - When originally tested, the faster you run the wetter you get.

  • The original result was "busted," but when revisited in episode 38 it was changed to "confirmed."[1]



  1. This is the first myth to feature Buster, who was purchased by Adam to act as a stand in (sit in?) for Jamie .[2]
