from discovery magazine:
While it may not have been a traditional magic act, Harry Houdini died literally at the hands of a physical "trick" he performed -- and a bad case of appendicitis.
Before a performance, two college students reportedly asked Houdini to demonstrate his physical strength "trick" of being able to absorb numerous blows to the upper body without injury.
The impact on that particular day was enough to burst the famous magician's already inflamed appendix.
Houdini died on Halloween in 1926, after surgery failed to save him from the resulting peritonitis. He was laid to rest in the prop casket he used to perform his famous "buried alive" illusion.
