Screen grab from video posted by @TansuYegen A group of Chinese students has captured global attention after successfully launching a homemade two-stage water rocket built from a simple cola bottle. The launch, powered by water pressure, shows the rocket soaring into the sky, separating mid-air, and deploying a parachute for a safe landing. A video of the launch has gone viral, drawing widespread admiration for the students’ creativity, teamwork, and technical skills.The video was shared on X by user Tansu Yegen with the caption, “In China, students made a two-stage rocket using a cola bottle and water pressure.” Since being posted, the clip has garnered over 1.2 million views.Using basic materials like plastic bottles and water, the students engineered a rocket based on air and water pressure principles. In the launch, the first stage propelled the rocket upward using pressurized water. At a certain altitude, the second stage separated and continued its ascent using stored pressure. A parachute then deployed, allowing the rocket to descend safely, demonstrating complex physics concepts such as Newton’s laws of motion, air resistance, and pressure.Social media users, particularly from India, flooded the comments with praise and introspection. One user wrote, “And we are still struggling with basic education and basic necessities for our citizens,” while another said, “Aur hamare yaha ke bacche..”A retired engineering teacher added to the discussion, saying, “I’ve probably seen 5,000 water rocket launches in the past 25 years. This is very cool, nice two-stage with successful deployment of a parachute. The parachutes are quite tricky.”
