Thank you for the response! I was actually planning on using a large bore flexible coupling pipe between the two pistons. When you say could the projectile "be the piston" are you thinking about loading the projectile into a tube (somewhat like a potato gun) and having the pressure created from...

Yes I can. What I am really needing help with is determining the proper dimensions of the pistons. Should the bellow piston have a greater working volume than the striking piston? Should the bellow piston have a greater bore diameter than the striking piston? I am just trying to achieve the best...

When the cup is at rest, the force of gravity pulls downward upon the water. At the location of the hole, there is nothing to balance gravity's force and prevent water from pouring out of the cup. However, when the cup is in free fall, the water will not leak. It is merely falling to the ground...

Hello my name is Aaron! I am a high school senior from northeastern Kentucky designing a pneumatic system of sorts for a science competition and need some help. I will be building a device that converts gravitational potential energy, from a falling mass, into air pressure (or possibly the...
