BUT BRAYDEN HAS MAJOR LEAGUE TALENT!  IT'S JUST THOSE UNFAIR PITCHES THEY ALLOWED FROM THE OTHER TEAMS, WHAT WITH ALL THEIR CURVE BALLS!  IF YOU WOULD JUST THROW HIM FAST BALLS, YOU'D SEE HOW HE'S A FUTURE HALL-OF-FAMER!   [All of this is shouted from out the window of a shiny jacked up F-350 that has never gone farther off-road than hitting a pothole in an Applebee's parking lot one time]

It was some serious shit - manhole covers were blown off and dancing on the fire plume. That's some serious pressure and flow to lift a manhole cover

Copper expands to 67,000 times it's original volume when it vapirizes. You definitely don't want to be in the line of fire during even a small arc flash.

See military application shaped-charges, ie. known as HEAT rounds or EFPs.  Conical copper liner, when detonated turns into a molten mass with velocities over 20k fps.  It was also the genesis for modern composite armor or the reactive armor we see all over UA/Russian tanks.
