Drain radiator with a fitting and hose?

[DerBenz]

I'd like to drain my radiator but don't want to let the old coolant spill on the ground *AND* I want to get the old stuff into a couple of new containers - I expect about 3 gallons total.

I'm thinking maybe I could use some kind of a valve that would screw into the drain hole like the regular radiator plug does and then attach a plastic hose off of that which I could use to control the liquid coming out .

Maybe a hardware store might have some kind of valve? Does anyone know the size of the hole that the radiator plug screws into? Any other ideas for a good way to control the flow of the old fluid out?
