WATCH: Metalworker sick of 9/11 truthers shows why 'jet fuel can't melt steel beams' is bullsh*t

A metalworker set out this week to prove once and for all why the argument that 9/11 must have been an inside job because "jet fuel can't melt steel beams" was bunk.

The man said that he was taking time out of his job at Purgatory Ironworks to shoot the video after seeing the conspiracy theory on his Facebook feed one too many times.

"If it was a conspiracy, I do not care," the metalworker explained. "What I am upset about is the retarded metallurgical things that you guys are saying."

"If you hold this up as reason for conspiracy, you are an idiot," he said, demonstrating that a piece of structural steel that had been heated to 1800 degrees could easily bend in his hands.

"Check it out, it's a freaking noodle!" the worker added. "You're argument is invalid. Get over it."

Popular Mechanicsnoted that his demonstration was entertaining, but slightly flawed.

"He openly admits that the forge he was using heated the steel beam several hundred degrees above the temperature at which jet fuel burns," the magazine observed. "That, and he doesn't say how long the beam has been in the forge, or offer any evidence of the forge's actual temperature. His little experiment here is more party trick than perfect simulation."
