Airplane propellors are tapered towards the tip. So are some maple seeds. This design used the knowledge about weight distribution to make a longer, tapered model.
The model rotated more slowly than the standard origami model, but fell as fast or faster. This contradicts the hypothesis drawn from the experiments varying wing size, which is that a model with lower wing loading due to a larger area, that rotates more slowly, will fall more slowly, too. What other factors could be involved? What hypotheses might you make? How would you test them?
