Thread: what is this?

okay so today i was working on my rear brakes again. My car has been on jackstands for 2 days (tilting foward). Im looking in the engine bay to add more brake fluid and i noticed this run dripping from somewhere behind the intake manifold onto the transmission. I swiped my finger on the drip and smelt it and it was odorless and clear almost like it was water. I dont know but i thought maybe it was some water from the heat/ac? just a thought...any ideas?
