THE WATER PUMP
Hello there, did you know air is powerful? Yes, it is! Did you know we use air for electricity? The windmill gives us power by rotating. So now you know about air. The water pump uses air to pump the water out of it, let us see what we need to make a water pump.
1.A plastic bottle-empty
2.A scissor-to poke a hole
3.A straw-paper or plastic
Follow these steps to make a water pump:-
Step1: poke a hole in your bottle with scissors as big as the straw
Step2: put your straw inside the hole
Step3: pour the water into the bottle
Step4: blow air into the bottle. The water will come out of the straw
The explanation is:
When you blow air into the bottle it pushes the water, and it comes out of the straw.
