air propeller, not water propeller. I want to see if I can pull something with it

Yes..............
Good luck. If you up the voltage you will most likely burn the motor up. It will make a very distinctive ozone-smelling smoke :-)

You couldn't pull much. Real propellers are designed to take a lot of stress. That fan will start to fall apart at the screws and at the blade edges if you put too much torque on it.
The pressed wood in the blades might even start to unravel with chips flying everywhere when the RPMs get too high.

If you have a good fan it might move itself on a skateboard...Good air props are a bit of a tease to the eye..they have a variable pitch so they can be adjusted in-flight to achieve optimum performance..Unlike a fan which is set up to just move a little air around in the room....Also the tip speed of the airplane prop is much greater just because of its diameter and to get good tip speed on a fan you might lose a blade....Try the skate board......Good luck from the E...

A fan blows air forward, so the force from a fan when it is running is to the rear of the fan. It is trying to tip itself over backwards, not pull itself forward like a propeller.
If you put the fan on a skateboard which is a good idea, the skateboard should be blown backward.
(P.S. buy a looooong extension cord)
