Hand Made Air Pump

 500

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.

Material:

  • Large syringe
  • 2 valves
  • nozzle
  • drip chamber
