I knocked down a wall this past weekend to expand the living room. Since the wall was coming down, I took the opportunity to try what I've always wanted to: see how easy/hard it is to punch a hole through drywall (sheetrock). Turns out it isn't that hard. As long as you commit to it before throwing the punch, and punch through the wall (aim at spot 12" behind the wall), it doesn't hurt, and sheetrock is no match. If you do it with reservation and hit like a girl, you're going to hurt your knuckles and your wrist, and the sheetrock will laugh at you. The first punch only got through one side of the drywall. But I figured that was because I was aiming at the surface of the wall. After I decided to aim 12" behind the wall, I threw one punch (on a fresh patch of wall) and went all the way down to my elbow, waving my hand on the other side. Seems like I did not put forth any additional effort; the follow-through did the trick. I was also able to smash a good sized hole with my head. (I do not recommend this). The follow-up experiment was to see how fast I could create a doorway with my bare hands and walk through it. I did it in under 30 seconds. Punch a hole, pull on the sheetrock around the hole, and you can pull large chunks in no time. Then just kick down the other side with your foot. So I'm wondering how many people have died in burning houses because there was a fire at the bedroom door, and they didn't realize that they could make another door anywhere they choose (along an interior wall). It should be a piece of cake for an able bodied male of any age, and with enough adrenaline and confidence, probably a feeble aged female too. Also makes me feel less safe. If I can get out in 30 seconds, that means someone else can get in in 30 seconds. Of course, the cardboard door with pot-metal latch is no match for a determined assailant either, but beefing up this door would be time wasted. Makes me feel like I live in a paper house.
