Origami Maple Seed
This origami (folded paper) model of a maple seed was developed at the 1997 Salish Workshop on Improving the Preparation of Science Teachers. The exercise titled "Maple Copters" was focused on the analysis of the behavior of maple seeds as a means of assessing the success of teaching the scientific method to students. However, my interests in design and technology as a method and a paradigm to support science, and as topics worthy of study on their own, led me to develop a reliable & consistent working model of a maple seed. Following my personal goals of simplicity and elegance, I wanted to build a model that could be assembled with the minimum number of tools and supplies, and that would autorotate reliably. I also wanted a model that could demonstrate the parameters involved in problems of aerodynamics, seed dispersal, orbital dynamics, and color recognition, just a few of the things that I saw could be taught with a whirling device. Here are the instructions to make such a model. It is best built out of Andes® mint wrappers. Their thin foil holds the shape of the folds. It can also be built using aluminum foil, origami paper, regular paper (with a glue stick to ensure that the last fold sticks), or thin paper. Thick paper doesn't work very well. Note that all the red lines indicate a "valley" fold, with the paper on either side of the line folded upward. For those who want to make one the size of the Andes® wrappers, but who can't get them, the wrapper measures 55mm wide x 62mm tall. Have fun! Instructions:

Grasp the finished model at the broad end of the wing opposite the weighted "seed" end, and toss it upward with a flick of the wrist to set it rotating. The model will spin to the ground. Or, to start it autorotating, hold it over your head by the broad end, "seed" end up, and drop it. It should autorotate within two feet.
