Hand Made Air Pump


Hand Made Air Pump you can learn how to make an air pump using basic techniques. This project is great for learning air pressure concept at school, library or home. Its a science exhibition project.

How does it work

In this air pump we attach two valves in it. The valve attach with nozzle is outlet valve and the valve without nozzle is inlet valve they both are attach in opposite direction to each other, so that only one valve is open at one time. When we pull the syringe the outlet valve is closed and the inlet valve is open, it suck air inside the drip chamber. When we push the the syringe the outlet valve is open and the inlet valve is closed, the sucked air transfer into the balloon from the outlet valve. This process is repeat again when we push and pull the syringe.
