Cantigny Catapult Contest

Visit the Catapult Contest website

Overview

Catapults have a long history in warfare. We want you to build a working version of these war machines. There are three different categories you can compete in, distance, shot group, and accuracy or you can attempt to build a catapult which can do all three. Prizes will be awarded for 1st and 2nd place in each category. Most importantly, contestants get the chance to build a catapult, compete, and possibly earn eternal glory! This project is fun, exciting, and as easy or intricate as you want to make it.

Rules

  1. No ready-made kits. Each catapult must be designed, constructed, and launched by contestants.
  2. No part of the catapult can extend over 6 feet high. This includes the sling on a trebuchet. Click here for an example.
  3. All catapults will be launched on a grass field. They must sit on the ground. No tables.
  4. The catapult cannot be staked into the ground.
  5. All catapults will fling baseballs provided by the First Division Museum at Cantigny Park.
  6. Your catapult must have a triggering mechanism which will allow you to stand 2 feet away.
  7. No explosions or air pressure may be used to assist the performance of your catapult. In other words, the energy used to power your catapult must be provided by the device itself.
  8. Surgical tubing and bungee cords cannot be used.
  9. Any type of hurling machine is acceptable: Ballista, Trebuchet, Mangonel, etc.

Participants

  1. This contest is open to all catapult enthusiasts; no matter your age!
  2. Teams are allowed (and encouraged). No more than 4 people per team please.
  3. All participants must register in advance.

Scoring

There are three categories to compete in. Teams can compete in as many categories as they want. Either one category alone or in all three categories if they choose.

Distance: Each team will get 5 minutes to complete three launches. Teams will not be allowed to go over 5 minutes. The best launch will be used as your score. The longest launch wins.

Shot Group: Each team will get 5 minutes to complete three launches. Teams will not be allowed to go over 5 minutes. The object is to have all three shots land as close together as possible. The team whose three shots land closest together wins.

Accuracy: Each team will get 5 minutes to complete three launches. Teams will not be allowed to go over 5 minutes. There will be a "castle" made of cardboard building blocks, approximately 4 feet square and 5 feet high, placed 80 feet from the launch area. The team that hits the castle the most times will be the winner. If no team hits the castle then the team whose shot landed closest to the target will win.
