Exploding stair wells

Im making a simpleish office map and was wondering how hard it would be
to make the starirs wired with explsis so if u press a button all hell
breaks loose and the stairs blow up and colapse. Would this be
incredibly difficult or not?

Thanx for any help

theres a tutorial wich might help here --->http://egir.dk/index.php?page=vhe_pylon.php

but its for hl1 so i dont know if its very helpful

try making the stairs a func_breakable, and then making a func_button which triggers an env_expolsion, and the env_explosion triggers the func_breakable stair to break. YOu coudl add some fire too, and other fancy stuff to make it look cooler.
