This is a build event in which the team must build a "roller coaster," or a marble track. The rules contain all of the construction parameters, so it is very important to read those thoroughly. The ending score is determined based off of height, gaps, loops, and time. The lower the height is, the higher score you get. The larger the loops and the larger the gap, the higher your score. The ideal time score would be finishing at the exact target time, because anything above the target time gives you a penalty. However, this also means that if the target time is 30 seconds, 25 seconds and 35 seconds would both give you the same score. Highest score wins. You will be penalized if you don't bring a design and data log, however they have been known to not require those at some competitions, so check clarifications on the VASO website to be sure. If you aren't sure, bring both just in case! Helpful links are below, but truly the only things that will help you for this event are reading the rules and a plan that will gain you points. The sphere may only travel using its own energy; no magnets, springs, rubber bands, electrical devices, etcetera.Â
