Whirlpool in a barrel

would it be possible to create a whirlpool effect in a 55 gallon barrel, without any other means of power other than water draining, would it need a trap akin to a toilet to produce it, if its at all possible?

I have never done that experiment, but I think if you do put a hole in the bottom, the draining water will lead to a whirlpool because the flow tends to be unstable with repect to the rotational motion. The Coriolis force due the the earth's rotation will tend to make the whirlpool counter clockwise, but not always because tubulent instabilities could lead to the other direction
