How to make a DC motor water pump at home step by step video?

In this video, we will show steps by step video instructions on how to build a DC motor water pump model at home easy way.

Take a DC motor and attach a small piece of straw to it by making a central hole to the straw stick.

Using a knife make a central hole to the red color cap. Take the blue cap and make a small hole sideways with the help of a knife and insert a small piece of ball pen refill to it.

Insert the smaller red cap into the larger blue cap and then insert medium size straw through the central hole of the red cap with the help of glue gun.

Attach the larger blue cap having ball pen refill to the DC motor by passing the shaft of it through the central hole of the cap and stick using hot glue.

Next, inside the blue cap attach a small piece of straw to the shaft of DC motor with the help of hot glue. Attach the small red cap to large blue cap using hot glue.

Finally, attach the full prepared DC motor to the water bottle filled with water. Now connect the DC motor copper wires to the 9 V batteries.

You will observe that water will start to flow through the small ball pen refill attached to the large blue cap.
