Karen shows you how to build a laser beam projector. It will use a laser diode and two motors with mirrors attached to their shaft so that the mirrors are are spinning. When the laser beam hits the first mirror it turns it into a circle. That circle gets reflected off of the second mirror and it's projected onto the the wall into a kind of spira trap shape. Potentiometers will allow you to adjust the speed of the motors so that we can adjust how fast the spirograph is spinning.
