Being picky, he failed to blow the 5000A fuse with a 50,000A current. He 
provided such current for an instant, which blew the fuse partly. In a 
real application, the high current would continue flowing through the 
other elements of the fuse, a bigger current per element than rated, and 
the rest of the fuse elements would blow in cascade till not one would 
be left alive.
