It's not easy to collect all of the vapor w/o a sealed container, you're right. However, that's not really a mandate. As long as you can capture some clean water, then you're doing it. We did this in my 5th grade classroom, so it's not hard. Granted, we used a hot plate to boil the water and a large, flat, shallow pan full of ice held at an angle above the boiling water.
The water boiled. The vapor rose out of the container and then condensed on the bottom of the cold pan. Since the cold pan was at an angle, the condensed water ran down to one end and dripped off of it.
You'd need some other way of making a "cool" surface to do this method, but it doesn't have to be ice cold by any means.
It's perfectly do-able. I mean, distillation is part of the moonshine process. Informed, but not necessarily intelligent, people can do it in the backwoods with a couple of drums and some metal tubing.

If the alcohol is at 1%, you're going to want to distill that out and concentrate it, man!
