Speaking of wd40, I had a can resting on the front frame of my trailer about a week ago. The sudden drop of about 18 inches to the concrete of the can of WD40 for some reason puts a hole in the can like a damn geyser, and nicely coats the trailer, the hitch, the back end of my pickup, and me with a furious mist of dust collecting molecules the likes I have never prior seen.
Was surprised at the amount that came out, almost as much as how fragile the little Chinese made aerosol can would easily fail.
