An idea that we played with, but never really got working, was to have the top and bottom roller both connected to the same motor, using pulleys, but having the top roller geared somewhat faster. This makes it so you can suck the tube in, then continue to suck in and it will rotate up. Put a backstop so the tube can only rotate so far, and all you have to do is suck in till the tube hits the stop.
