I took a look at the video and I have to say after watching that it looks much easier than I thought so I'll give that a try. I so much don't like wasting anything. And using them for dusting is a great idea. Batting is always a little "sticky" so I can see why these are good for that. I'll put one in my car as the dash is always very dusty.
Love the snowball fight idea and I know lots of kids who would get a great kick out of that.
