In this tutorial, we learn how to build a magnetic stirrer from computer parts. This is a simple thing to make, and is great if you are going to be mixing chemicals and don't want to get your hands dirty. First, you will need to create a wooden box with the top empty. Then, place a computer fan into the middle of the box and pin it down. Place a magnet from the hard drive in the middle of the fan, then place a stirring rod on the glass that will go on the top of the wooden box. Now you will be able to use the magnet to stir anything!
