1. Prepare the Body
   Use a plastic bottle or a cardboard tube as the blower body.
   Cut the front in a narrow shape for air output.

4. Add the Switch
   Connect the switch in series with the battery for easy ON/OFF control.

   Make sure all connections are tight and insulated.

   Close the back of the blower with cardboard.
   Ensure the front remains open for airflow.
