The Putra Water Rocket Challenge is one of the component activities held during the Jom Sains @ Komuniti 2025 Carnival. This activity serves as a platform to inspire participants to explore new areas in science and technology. Participants are tasked with designing, building, and launching a water rocket to achieve maximum height and complete specific challenges. This activity helps develop students' talents to become more creative in utilizing technology while also attracting public interest in science.

In addition, through this program, participants will gain exposure to the importance of science and technology and foster an interest in conducting experiments to achieve success. Ultimately, it is hoped that this competition will nurture participants' interest in exploring science and technology more deeply. It is also expected that the competition will broaden their understanding of aerodynamics, physics, and engineering principles in a practical and enjoyable way.
