Take hydraulics to the next level in your classroom. Using a system of syringes, tubing, and three-way valves, you can build the Can Crusher, a mini version of a four-post hydraulic press similar to those found in manufacturing and testing facilities around the world.
Creating a mechanical advantage of 14:1 with fluid running through tubing and syringes, it easily crushes aluminum cans, paper cups, and other items. Two tubes – one to take up the water and the other to return it – rest in a cup of water. Pumping the small syringe forces fluid through the tubes and to the four larger syringes, creating a lot of force from a little input.
Assembly required.
