Each team builds exactly 6 missiles, utilizing precision straws as the missile body. Missiles are constructed during the time of the event, using only materials provided by WESO. Missiles are launched indoors at a fixed target, with each participant on a team getting an opportunity to launch. The accuracy of the missile (distance from target) on a team’s three best launches is used to determine the team score, with the shortest total distance from target being considered the winner.
