Instructions
Bend one paperclip to make it straight. Place a propeller onto the straightened paperclip. If the propeller is a rectangular piece of paper, then use the paperclip to puncture a hole in it and slide the propeller onto the straightened paperclip.
Bend one end of the straightened paperclip with needle-nose pliers. The result is a right angle with the end piece no longer than 1/4 inch long.
Place the center of the paperclip with the propeller at least 1/2 inch past the nose of the paper airplane.
Attach the paperclip with the propeller in that position to the paper airplane with two to three small pieces of clear tape, laying the tape pieces lengthwise over the paperclip.
