Bean Zipline Process

Four notecards, two beans, a meter of string, ten centimeters of tape, and two paperclips. Objective: move the bean a meter. Result: a zip line using all of the supplies (along with the help of a standing ruler). The process started out with the notecards, trying to figure out a way to stack them in a way that would create a workable zip line. Turns out flat notecards don't hold weight very well, but notecards folded into triangles- perfect. So with our triangular notecards, we made our zip line. We taped the beans to the paperclips, then we strung the paperclip on the string, and we expected it to fly- it didn't. The string was giving away too much slack, so we figured we needed to elevate one set of the notecards more. We placed it on a laptop; the bean was still not moving the whole meter. So the new objective was to raise the zip line more, we did this by taping one set of notecards to a standing ruler (38 inches tall standing ruler to be exact). We taped the other notecard to the table, and made sure the string was tight. Then came the real test, we placed one paperclip with the bean on the string, and it made its way successfully down the zip line. We tried the other paperclip, and it worked out perfectly, objective: complete.
