I know this will sound stupid but I want to be sure that this doesnt
blow up in my face (literaly). How do you make a simple circuit
consisting of capascitors to increase the volatage in a 12v DC supply?

You can't.

Sure you can, dumb ass.

You do it with an AC voltage if you use capacitors and diodes but not DC.

Charge two or more capacitors in parallel and then discharge them,
in series, into another capacitor. Do it fast enough to compensate
for losses and the load, and the voltage across the output cap will
rise to nearly n Ein, where n is the number of caps dumping into the
reservoir.

Compound charge pump, dopey donkey, No AC involved.

hmm, so what do you use to switch the capacitors? AC or DC

In the simplest instance, relays with DC coils.

Fed with DC ?
