I have this project for school and it is all about Pascal's Principle. Well Ive decided I would like to make a hydraulic lift to go along with my presentation and just need some help with the design. I figure I can make it out of PVC or Copper tubing, either way I dont mind buying most of the materials. I just need a sort of "U" shape lift that I think would work, my problem is that I dont know what I could use for the "piston" portion. If it came down to it I guess I could just use two different size seringes(sp?) but I dont want to settle for less. Any ideas? Not clear enough?
