..."Hair Dryer/Bath Electrocution: Simply put, if someone's in the
bathtub and an electrical appliance gets dumped in with them, the
movies state that it would give enough of a jolt to their system to
kill them. The guys did a good job of simulating the myth, and testing
the current as each item (toaster, curling iron, hair dryer, and
radio, among other things we didn't see) gets dumped into the test
bathtub (using a ballistics gel dummy with metal panels inside to
simulate the human heart). They ended up getting a few things wrong
with the test (like overestimating the amount of ampage needed to kill
someone and minor equipment goofs), but once those were solved, they
were amazed at how well the experiment proved the myth. About the only
object dumped that didn't give over the fatal amount of amps (which
was around 6) was the curling iron, and that still pumped out enough
amps to at least leave you paralyzed long enough to eventually
submerge into the water and drown, or bake to death from the
current....""
