Things You'll Need
- Construction paper
- Plastic yogurt lid
- Rubber bands
Paper airplanes are a staple of childhood fun. Kids love to send them flying across the classroom or competing with friends to see whose plane can fly the farthest. To send your plane on a warp speed mission, you can add a rubber band propeller to its front end. The propeller works by creating a slingshot effect, which sends the folded piece of paper into a fast forward thrust. With some basic household materials, you'll blow away the competition with other planes.
Making the Paper Plane
Fold and crease a piece of construction paper lengthwise. Open the paper so that the outside of the crease rests on your work surface.
Fold and crease the top right and top left corners of the paper so that they meet at the center fold.
Bring both folded corners of the paper so that they meet at the center fold. Crease both folds.
Fold the paper inward along the center crease. Orient the folded paper so that the diagonal line is on top. At this point, the plane should resemble a dart.
Bring the diagonal flap over to meet the flat bottom of the plane. Crease the fold. Turn the plane over and perform this step for the other side. Lift out the flaps to open the plane's wings and prepare it for propeller installation.
Installing the Propeller
Cut a tabbed hook out from a plastic yogurt lid. The tabbed part of the hook, which should be roughly the size of your thumb, will hold it securely inside the plane's crease. The hook should be slightly smaller than your curved pinky finger.
Insert the hook into front of the plane's central crease. Poke the hook through the base of crease so that it points toward the rear of the plane.
Staple the hook to the base of the plane. If your construction paper or plastic lid is thick, consider using two staples.
Place the rubber band around the hook. Support the hook with your dominant hand. Pull the rubber band forward in front of the plane using your opposite hand.
Release the hook to launch the plane.
Keep extra rubber bands handy so you can perform multiple plane launches.
