One day I found a propeller in my Knex box. My sister had a remote control helicopter that hasn't worked for a long time so I tore off the motors and connected a straw that was the same size and taped it and ran the wires through the straw and put Knex on it.
<p>That's pretty cool. Does the propeller actually propel the boat through the water? </p>
<p>I can't get the motor to turn so I don't knew if it will work </p>
<p>I have not tried it yet I will send a picture later</p>
