<human>: How to make a water pump?
<bot>: To make a water pump, you will need some basic tools and materials. Start by gathering the following items: a drill, a metal pipe, a motor, an impeller, and a pump housing. Next, measure and cut the pipe into two pieces that are each about 12 inches long. Drill holes in the end of each piece of pipe, one at either end. Attach the motor to the first piece of pipe with screws or bolts. Then attach the second piece of pipe to the motor so that it is perpendicular to the first pipe. Finally, attach the impeller to the end of the second pipe. Place the pump housing over the whole assembly and secure it in place with screws.
