How many students can be on a team?
One to four students. The team's division comes from its oldest student's grade: a team with anyone in grades 9–12 enters Senior, and a team of grades 4–8 enters Junior.
Can one school send more than one team?
Yes. There is no limit on teams per school. Each team registers separately and gets its own kit.
Who can be a team leader?
A teacher, coach, tutor, parent or guardian, or another adult with the students' guardians' permission. The leader registers the team and is our contact for it.
Does it cost anything?
No. Registration is free and every team can ask for a free kit. Admission to MOST on the day is free for students and families who arrive before 9:30 AM.
How do we get our kit?
Tick “Request a kit for this team” when you register. Kits are ready right away, while supplies last: collect yours at the MOST front desk Thursday–Sunday, 9:30 AM–5:00 PM, or by appointment Monday–Wednesday and outside those hours — email the coordinator (see Contact below).
Can we add our own materials?
Only more of the approved materials: craft sticks, rubber bands, plastic spoons, clothespins, a wooden dowel rod, and school or wood glue. Anything else, hot glue included, is not allowed.
Can adults help the students build?
Yes. Teams build together with their leader, and support sessions are available by appointment. Let the students lead, though: they explain their design to the judges on the day.
What if we can't come on Saturday?
New for 2026: school teams can test on Friday, October 16 instead. Choose Friday testing on the registration form and we'll be in touch to schedule it.
Does an adult need to come with the students?
Yes. Every student needs an adult (21 or over) with them on the day. If the team leader is coming, they cover the whole team; if not, the registration form asks for a chaperone or an adult for each student.
Do we need to bring anything on the day?
Your finished catapult and your team number, which is in your confirmation email, for check-in. The ping-pong ball is provided at testing, and a repair and supply station is on site if anything breaks on the way.
What if our catapult doesn't pass inspection?
Judges check every catapult against the specs before testing, and you can fix it at the repair and supply station. A catapult that is still off-spec can be tested, but it is not eligible for awards.
