Excellent for office place battles.

We're actually building a large trebuchet / catapult here at the
Hall of Science for some programs in October (launching 8lb water containers
around 200ft).

We'll be launching a siege on the USGA tennis center next to us not long
after.

Any other institutions on this list have working catapults that are
frequently used throughout the year? Wouldn't mind asking some questions
about things like storage and durability.

Thank you.
