Two special effects guys set out to prove or disprove various urban legends by re-enacting the myths.
So far we've seen the JATO rocket car in the desert, Mikey dies from eating too many Pop Rocks (simulated with a pig stomach), and the tower repairman accident report (gets hit by a toolbox on the way up and down while holding a rope).
Current episode is "pee on the third rail and get electrocuted", which involves a dummy made of ballistics gel (same electrical properties as the human body), a bionic bladder (anatomically correct), and 250ml of donated urine. They've done tests on the urine to determine the resistivity, and have calculated (and experimentally proven) that a stream of urine will conduct a current of 65 milliamps when driven at 650 volts, more than enough to cause a heart attack.
Very funny and entertaining. Somewhat like Junkyard Wars meets The Darwin Awards.
