I was very excited when I got my first Lego Technic pneumatic set during the 90's. I got fascinated a pump that creates pressurized air can move various parts for this set. Over the years Lego came out with an air tank. The air you press with the pump gets stored in the air tank for future use. I got amazed there air gauge you can attached to measure how much pressure is stored inside.
There also kits that can control pneumatic with a motor though I prefer the non motorized version since you don't need batteries.
