Marksmanship
The DIY Shooting Challenge is a hands-on STEM competition where students design and build a mechanical projectile device using only limited provided materials. Inspired by Sustainable Development Goal 9, it encourages participants to apply science and engineering concepts in a practical, real-world context.
Age Categories
Junior Primary (7 - 9 years old)
High Primary (10 - 12 years old)
Junior Secondary (13 - 15 years old)
High Secondary (16 - 19 years old)
Adult (20+ years old)
Purpose
The DIY Shooting Challenge aims to inspire and challenge participants through a hands-on engineering experience that fosters essential STEM skills by applying science concepts learnt in class. Aligned with Sustainable Development Goal 9: Industry, Innovation, and Infrastructure, this challenge compels participants to transition from theoretical STEM concepts to practical industrial application.
The competition focuses on three core pillars:
1. Engineering Innovation: Developing bespoke mechanical trigger and propulsion systems beyond basic instructions to innovate their own mechanical trigger and propulsion systems, mirroring the research and development cycles found in modern industry.
2. Technological Proficiency: Constructing high-performance prototypes from fundamental raw materials develop the technical skills necessary for advanced manufacturing and infrastructure problem-solving.
3. Resource Stewardship: Optimizing design efficiency to maximize output while minimizing material waste promoting the sustainable and efficient use of resources—a core pillar of modern industrial innovation.

Task/Mission
Participants will design and construct a DIY gun and bullets using only provided materials. The objective is to shoot a designated target placed at a distance of up to 3.5 meters and a height of up to 2 meters. Participants must conduct three official shots to determine their accuracy score.
Participants must use uniform consumable materials provided during the session. For evaluation, participants must complete their 3-shot official test under the supervision of a judge.
In short, this is a mechanical engineering competition designed to evaluate participants' abilities in structural innovation, ballistic physics, and resource management. Participants are tasked with the design, assembly, and operation of a functional projectile system under strict time and material constraints. Technical Specifications & Construction
Time Limit for Construction: A total of 120 minutes is allocated for the full development cycle: design, assembly, and iterative testing.
Material Limitations: Only officially sanctioned materials provided by the organizers are permitted. The use of external tools, adhesives, or pre-fabricated components is strictly forbidden. Mandatory Gun Specifications
Trigger Protocol: All devices must feature a functional trigger mechanism. A mechanism is defined as "functional" only if the projectile release is exclusively initiated by the trigger's activation. Devices capable of spontaneous firing or manual release without a trigger will be deemed non-compliant.
In short, your gun must have a working trigger to fire the bullet. To be considered "functional," the gun must only fire when the trigger is pulled. If the gun can fire on its own or without using the trigger, it will not count as a functional mechanism.
Manual Reloading: Manual reloading is permitted between each of the three official attempts.
Ammunition Management
Shot Limit: Participants are granted exactly 3 shots during the official scoring period.
No Reuse: Bullets that have already been fired cannot be picked up and reused for subsequent official shots.
Target Dimensions
The target will be placed at a maximum distance of 3.5 meters and a maximum height of 2 meters.

Rule Zero
RULE ZERO – Zero Tolerance & Common Sense
In all CIPTR1X competition, Rule ZERO applies, which states:
➤ "If you are not sure whether something is allowed, then it is probably NOT allowed."
All rules are based on common sense, the spirit of the sport, and the safety of all participants.
Any deliberate misinterpretation, violation of the meaning of the rules, or attempt to exploit gray areas for unfair advantage will not be tolerated and may lead to team disqualification from the competition
