We did a paper airplane test in 5th grade. We split into teams and made them like McDonnell Douglas, etc. First, we saw how many airplanes we could make and then how far they flew. Everyone was rushing to get the planes made, but I took my time and measured them to make sure every fold was done right. My planes flew the farthest, and our team won the government contract. The moral of the story was that haste makes waste.
