In a jaw-dropping display of creativity and engineering, a group of Chinese students has successfully launched a two-stage rocket made entirely from plastic cola bottles and water pressure — an innovation turning heads in science classrooms and online platforms worldwide.
The homemade rocket, built using recycled cola bottles, valves, and pressurized water, achieved remarkable height and stability for a project with zero combustion and no fuel-based propulsion. The students employed basic principles of Newtonian physics, using water pressure to launch the first stage, which then detached mid-air to allow the second stage to soar further.
The event, captured on video and widely shared on social media, is being hailed as a brilliant demonstration of STEM education in action, combining fluid dynamics, aerodynamics, and multi-stage separation — all using household items.
Educators and scientists praised the achievement, calling it a “perfect blend of play and precision.” The project is now being considered for national science exhibitions and has sparked interest in promoting low-cost, high-impact science experiments across schools in China and beyond.
While it may not be heading to space just yet, the message is clear: innovation doesn’t always need millions—it needs imagination.
