Catapult Competition

How to Participate

It’s easy and free. Contact Kyle Kabakjian, youth leader and marshal of the event, by email at kyle@gotwentyfourseven.com letting him know you would like to enter the contest, including in the email all the participants on your team and the type of catapult you will build (to the best of your knowledge). Do so quickly as there may be a limited amount of teams who can enter. Then, gather your team of engineers and assemble your catapult, and show up to Twentyfourseven with your catapult March 14^th before service and be ready to shoot. Participants are responsible for providing their own materials.  Further instructions will be given regarding the competition, scoring, rules, machine regulations, and times of the event once Kyle receives your email application; so submit your emails to get this information before you begin building!

The English Battle

The goal of the contest is to build the best catapult. Each catapult will be judged in three categories, Distance, Accuracy, and Style. The winning team takes home the $100 prize!

What will you shoot? Two types of projectiles are allowed: Water balloons or dead horses. (Note: Dead horses are more historically authentic catapult projectiles, but water balloons are somewhat easier to procure.) Participants must supply their own water balloons and/or horses.

Teams will be allowed a limited amount of time to fire practice shots before the event begins.

Specifications:

There are several types of hurling machines you can build: Human Powered (Traction), Spring Powered (Tension/Torsion), and Gravity Powered (Trebuchet).

Rules for Human Powered and Spring Powered Machines:

A moving lever, powered either by a human or a spring must hurl the projectile. Projectiles may not be thrown by hand.

Rules for Gravity (Counterweight) Powered Machines

The counterweight must be immobilized with hooks or straps except during the actual competition hurl.

Projectiles

Water filled balloons are the approved projectiles. While big balloons make it easier to hit the target, they are harder to hurl without breaking. Use of a sacrificial sling (a string or cord with a loop tied to the balloon that travels with it as it is hurled) is allowed, but note that the sling pulls hard on the balloon and may cause it to break prematurely. Participants must supply their own water balloons and string.

General Notes

Teams must supply own tools and materials. Teams must supply their own water balloons. Cooperation is as important as competition! Help out your fellow hurlers by loaning tools, providing advice, and offering encouragement. Good sportsmanship and a good attitude is the most important thing you can

bring!
