Everyone wants to be an evil scientist and create their own little nanobot. Well that is hard but building something cool and entertaining with a few parts isn’t. The bristle bot is a self-propelled little thing that scoots along the floor. It isn’t hard to build and you can find the parts in a lot of different places. The motor is the same one that you find in a cell phone that can vibrate (we don’t recommend tearing into a cell phone, especially one that works). This activity was developed by Windell Oskay at Evil Mad Scientist. Check him out. http://www.evilmadscientist.com/article.php?story=bristlebot
