Model aeroplanes are toys that replicate actual aircraft. Like many real aeroplanes, models are often driven by a propeller. Model propellers use horizontal lift--the same force that real propellers use to power actual aircraft--to drive the toy aeroplane forward. You can use a few common household items to make a simple, yet effective model aeroplane propeller. You can make this propeller in a few simple steps.

Use your scissors to cut off the top and bottom of the two-liter bottle. Cut just below where the bottle goes from curved to straight.

Use your scissors to cut out two propeller blades. Cut the blades out on an angle to add a slight twist to the blades. This is to counteract the adverse effect of the outer edge of the blade travelling faster than the inner edge of the blade, which would otherwise make the propeller unstable.

Twist one paper clip in half, then bring it over itself to create a loop in the middle. Form a "T" shape by bending the end of the other paper clip around the first paper clip's loop. Use pliers to tighten the second loop around the first loop.

Bend both ends of the first paper clip into large loops. Tape the ends of the plastic propeller blades to the outside of the paper clips.
