For some reason, paper airplanes never seem to fly too well, which is why it's about time that something like the Power Up Electric Power Module came out.
Paper planes are annoying to teachers, but if you really wanted to get under their skin, you'd take advantage of the Power Up Electric Power Module. It's basically a miniature propeller that you can attach to your plane so that you can actually give it the power of flight. The item operates via battery, which requires a 20-second charge before you use it. This should provide about 90 seconds of flight, which should be more than enough time to test your teacher's patience. Having this in the class or the office would be incredible for passing time waiting for printing to finish or during a boring lecture.
