Making a paper airplane is a classic craft for all ages. Grab a sheet of A4 paper, fold it in half lengthwise, then unfold to leave a crease. Fold the top corners down to meet the crease, forming a triangle. Fold the new top corners inward again, then fold the paper along the initial crease. Finally, fold the wings down from the center. Adjust the wings for balance, and your airplane is ready to fly. This simple toy encourages creativity—decorate it with markers for a personal touch. It’s cheap, easy, and provides hours of outdoor fun.
