Airplanes--not just of the paper variety, spiral for all sorts of reasons. Instability may be a cause, or perhaps the aircraft has stalled and entered a spin.
In a paper spiral, energy is transferred in the form of mechanical energy as the paper spiral unwinds and falls due to gravity. This mechanical energy is converted into kinetic energy as the spiral moves.

Design can effect paper airplanes just as it does real aircraft. Paper airplanes can be a huge variety of designs and be specialized, just as real aircraft. This can be for style orfor performance.
When you hold a spiral paper over a lit candle, the heat causes the air within the spiral to rise, creating a mini updraft that makes the spiral rotate. The rotation is caused by the temperature difference between the inside and outside of the spiral paper.
The number of paper airplanes possible would be a function of their individual sizes. It could be one paper airplane, or many.
