Blender!

Good news! I decided to make a mini blender. Now that I think about it, it's actually simpler than I thought (although I'm not making it turn both ways). I've sketched it, which is the easiest way to figure out how something works. It has a switch that you turn on (it's supposed to be a button, but we don't have any), and that makes the motor turn. I had to learn how to use a battery pack with a switch, though.
