pressure activated means when you step on it it blows
i cant make plunger surface bigger because the holes will be blocked and then the paint won't mark them

yes you can. Redrill holes at angles, an put in 8 an make them smaller. Thee angle will help, but the smaller holes increase pressure. Cover more area.

Another reason why trip wires are better. Nobodys foot can cover it all

Pretty nice. The only problem I see with it (If I understand how it works correctly) is that it is essentially running on unregged CO2, which is quite high pressure and cold when it is released. In PVC that's not such a great idea. (I understand the holes let it vent instantly but if you are unlucky there's the potential for somthing to go wrong). Also how securely held is the moving bit that holds the CO2 cartriage? Last thing you want is it to fly off and hit somone (again, I may be misunderstanding the mechanism here).

Other than that nice job!

I wonder how much deeper the ocean would be without sponges.
Right now I'm having amnesia and deja vu at the same time. I think I've forgotten this before.
