I'm gonna get all over this. This is my kind of project.
I'm with ya on the soap crystals but what the squat is cotton wool? We seem to be separated by a common language.;)
I suppose it's cotton batting that my first, current and last wife has in the bottom drawer of her secret stash of stuff. (She has no idea I know what's in there)
Now I know why BB can't do his head from last year. He'd have to break down an purchase a cordless drill. That worn out old thing he has has a cord on it. Cheap skate.
Also I'll preserve a large ant hill out front, fall and spring is when I kill the critters.
The neighbors are gonna love this project. At least it doesn't make noise.
