-Once these parts were in place, we finally began the testing stage. After a few "dry attempts" we concluded this: The speed at which the pipe arm moves is too fast, we need a way to slow the arm, and therefore the pipe attached to the arm, without compromising its end destination. We knew we could increase the friction with even more pulleys, find a less tense spring, or add counterweights to the arm until the speed is where we like it. We all decided on the addition of weights to help the arm move more smoothly. There's a video of the test at this link!
