Papercupter competition

Finding the best design for a papercupter is not easy as there are many designs, for instance, with longer or shorter flaps, curvier or straight, only a few flaps or as many as you can get from your paper cup. The number of different papercupters is infinite and so finding the one that spins the most or the one that stays in the air for the longest time is impossible.

There are some papercupter designs which clearly won’t work, for instance, one with flaps so small that it does not make the papercupter spin as it falls down, or one with so many flaps that they become thin strips of paper with no air resistance.

Last week we were able to play a papercupter competition (during the 2017 De Morgan Dinner) and more than 50 different designs competed against each other. The papercupters which made it to the final round had, in general, only a small number of long flaps.
