Main mechanism!

We introduce to you the Lego in "Lego Bubble Blowing Machine." The servo has been masked under legos, but it's function can clearly be seen in this video. It serves as a slider between two ends of lego land. This setup was built upon the older idea of the two cups in one of the earlier posts. The purpose of it all is still the same, though. Imagine bubbles at one end and a fan at the other. Now imagine a bubble wand extending from the servo in which will dip into that awesome solution of soap, and then transfer itself to the other side to create bubbles!
