TWIN SYRINGE PUMP | Urdu

Medical technology produces a hell of a lot of waste. With two syringes – one fat, other thin you can make a lovely pump. Remove the plunger of a 6-ml syringe and then remove its black rubber piston. 
Remove the plunger from the small syringe and place a ball-bearing in its barrel. Place its black rubber piston as an end stopper. The steel ball will act like a valve.
Make a hole in the black rubber piston of the big syringe and stick it with rubber glue on the nozzle of the small syringe. Even after gluing the rubber piston you will be able to see the nozzle hole very clearly. 
Make a hole near the end of the small barrel. This will be the Delivery Port – the hole from which the water will come out. 
Now, put another steel ball in the big barrel and then push the whole small syringe into the big one. 
The pump is almost ready with two valves, a barrel and a piston.
Place the pump vertically in a mug of water and push-pull the small syringe a few times.
Soon water will gush out at a very high speed.
