Super Antics 17 by Kerry Callen
This was totally not what I was going to post this morning, but I was trying to put names on certain classic superhero poses, like the Strongman breaking Chains, and wound up here
Be Yourself
Unless you can be Superman
Then be Superman
By the way, Superman used to kinda break chains at the weakest link or even with his hands, but power creep, and then there were exploding.
Nerds might introduce "tactile telekinesis" at this stage in the conversation, but ... nerds.
However, just how strong would Superman need to be to shatter chains like this? Not at the weakest link, but like BOOM!
At this points, physics nerds begin to argue and take out their Texas Instruments graphing calculators and Physics 101 books.
Let's say 'a lot'
He just needs to be fast enough that the chain needs to break at multiple points to handle the stress - the faster he moves, the less time it has to react, and the more points it has to shatter.
