When you’re dealing with a lot of tiny metal pieces, a magnetic tray can be a lifesaver. No need to go buy one, though, if you have a cheap plastic bowl and a magnet lying around.
Magnetic trays are great for screws, nuts, bolts, and even bobby pins and sewing needles. They’re not exactly expensive to buy, but if you have some simple items lying around, Instructables user Engineer of None might save you a trip to the store and help you get a use out of some junk lying around. All you need is a plastic bowl or tray, a magnet - he uses a magnet from an old speaker - and some duct tape. Now all your little tiny parts wont go rolling around all over the place. Check out the complete guide at the link below.
Whether you're taking apart your car or your laptop, your screws, nuts and bolts of all sizes are better off in this magnetic bowl than pretty much anything else, where gravity, wind, and other natural phenomena could steal them from you.
