Yeah, the problem here is finding the mass (and speed but that can be decided upon later.). The roadblock I face is pixelscaling. Like, I've tried using paint on my computer (which I'm not sure if it works anymore or not it's been stuck on a black screen anytime I boot it up), but the panels I'm using are far too large to get any reference shots for the tsunami scaled.
i do too if held at gunpoint but eh,for a tsunami, ya could half ass it and do PE or KE but, you'd obviously need mass and speed, but once ya have those, it's easy af
