Step 2Making The "Circle Maker"
Before we open up the glass to get inside the Etch-A-Sketch, we fist have to make the device that will be making the circles.
For those of you who don't know how an Etch-A-Sketch works, the knobs move a plastic stylus that scratches the super sticky aluminum powder off of the glass.
So we want to make a plastic circle with sharp edges that will scratch the powder off the glass to form a circle when you twist the knob.
I used the plastic ring from a 2 Liter Soda Bottle and taped/glued it to metal wire from a hanger to make this device, but you can experiment with other stuff to get similar or better effects. Just make sure you're able to twist the plastic circle easily.
You should use a scissor to scratch the surface of the ring so it'll be rougher.
