Hi guys. I'm *attempting to make* an archimedes screw for my engineering project. The only stipulations for this project are as follows: Create a machine that will move water from point A to point B The machine must be powered by my professor's desk fan. So, I bought a small wooden dowel, some clear plastic tubing. I wrapped the tubing around the dowel countless number of ways. I attached a pinwheel at the top of the dowel, so as to utilize the desk fan in powering my machine. I see seven year old kids making archimedes screws on youtube...I absolutely cannot get mine to work. I have tried wrapping the tube around the dowel very loosely, very tight. I am making sure the structure of the tube is in tact....The tube will pick up water but it will not move UP the tube. I have even tried changing the angle of the whole structure to help the water move up the tube. I am beyond frustrated. PLEASE HELP!
