this is what i think. i was thinkgin about this during class yesterday! haha.
okay.
so i'm guessing the board is non-porous, which means that the ink doesn't have any tiny gaps to go to. so it just stays on the board, dries, but because the board is non-porous, it wipes off easily and usually, without a trace.
i hope this makes sense.
it did in my head.

i think it erases easy because the ink turns sort of dust-like after u write on something so its easily removed
