If you count sandbags as dams then I guess you can build dams out of sand.
This isn't the same as the other one. It's different in terms of the actual build of the dam and the composition of the terrain, the cooling thingy is not filled with rubidium either.
Dams are made of several things, but the main components are concrete, rebar, and pure labor.
Crra11: No it ain't. Seriously, it really isn't.
ACUTALLY, DAM IS MADE OF CONCRETE OR SAND
I'ts the same save another again, and againg, and again, and again, and again, and again, and againd, and again
I wouldn't see why he'd be pissed, because all you took was the concept and rework it.
