Splash Rocket

Splash Rocket - TechFEST'26

About The Event: Splash Rocket is organised as part of techFEST'26, the Annual Technical Festival of SLIET. The event is a two-round challenge where participants launch water rockets for maximum distance and precise targeting. The challenge focuses on physics, pressure, and precision using water and air.

Number Of Rounds: 2 rounds.

Round 1 - Distance Round: Each team will get 3 launch attempts. The objective is to achieve maximum horizontal distance. The farthest valid launch will be considered for scoring. Teams must use only the rocket and materials approved by the organisers. Launches must be performed only from the designated launch area. Teams must follow all safety instructions during preparation and launch. Any unsafe or unauthorised modification may lead to disqualification. Distance will be measured by the event coordinators/judges. In case of a tie, an additional tie-breaker launch may be conducted. The organisers' decision will be final.

Round 2 - Targeting Round: Each team must launch its rocket toward the designated target. Targets will be placed at predefined distances. Teams will receive the number of attempts specified by the organisers. Points will be awarded based on proximity to the bullseye. Higher accuracy will result in a higher score. Only launches from the designated launch area will be considered valid. Teams must follow all safety instructions during preparation and launch. Any unauthorised modification or unsafe practice may result in disqualification. The judges will determine the landing position and final score. In case of a tie, a tie-breaker launch may be conducted. The organisers' decision will be final.

Rules & Judging Criteria

Team Size: 1–3 members.

Time Limit: 2 hours to design and demonstrate the model.

Material: Only approved materials can be used. Teams must build water-propelled rockets using safe, non-combustible materials. No chemical propulsion is allowed. Rockets must use only water and air pressure for propulsion. The launch mechanism must be manual and safe to operate by participants. Each team will get two attempts per round; the better result will be considered.

Evaluation Criteria: Maximum Horizontal and

Vertical Distance: 50%.

Innovation and Design: 20%.

Presentation & Explanation: 15%.

Discipline and Behaviour: 15%.

Component Limitation: Participants are allowed to use only approved materials for rocket construction and launch setup.

Plastic bottles: 1–2 litre capacity. PVC pipes for the launcher frame. Bicycle pump or foot pump for air pressure. Water as fuel. Rubber corks, valves, or clamps to seal and release pressure. Tape, glue, and zip ties for construction. Fins, cones, and other aerodynamic attachments made from paper/plastic. Measuring tape or scale for optional self-testing. Markers, flags, or cloth for target identification. Metallic or combustible components are strictly prohibited.
