Balloon Bottle Pump | Hindi

Here you can see the pump in operation. The pressured air from the balloon pushes water up the straw! To make this simple pump you need a plastic bottle, a flexible straw, rubber glue and scissors. Make a small hole, 4-cm below the bottle neck. Insert the flexible straw through this hole. Later seal the joint to prevent any leakage. Then fill the bottle three-quarters with water. Inflate a medium size balloon. Stretch the inflated balloon’s mouth and fix it on the bottle mouth. Immediately, the pump will start pumping water through the straw. The pressurized air from the inflated balloon will lift water up the straw. All the water from the bottle will be lifted up! It’s a very simple and elegant pump and will be a sure hit with young explorers.
