I can say with certainty he doesn't care about how things work. It's more of a 'signs of damage' kind of thing. He likes seeing the aftermath of the destruction he caused. There are a lot of holes in my drywall from that. Also, he threw eggs at the neighbors houses (that was a fun time). Drops items off the deck to see how they break (including a dog once). I've tried redirecting him by putting together chunks of legos and letting him smash those. Sometimes that works. The least destructive redirection I've got is him simply pouring a cup of water from the deck to the patio. The splash of the water seems to calm him a bit. He has a major attraction to water.
