Imagine getting stuck on The Red Planet like our very own Marvin. No fuel. No resources. Connection lost. Go through the basic textbook principles of Aerodynamics and Physics and guess how water can help you sail through this. Get a bottle and water and let's see how far it goes? Create a water rocket and make it fly across the vast lands because where nothing helps, H2O does!


Design and Build a water rocket which can be launched at any angle with respect to the horizontal. The teams will be participating in two rounds and the winners will be decided on the basis of rules given below.


  • Maximum capacity of water rocket is restricted to 2L per bottle. Dimensions of the rocket can be adjusted accordingly.
  • Only plastic soft drink bottles are to be used for the rocket body.
  • The nose cone and fins should not be made of metal or any sharp surface. The rocket should be launched using a string from a safe distance, not with the help of hands. If a team fails to meet this requirement it will be disqualified from the event.
  • The water rocket must use only compressed ambient atmospheric air as its source of energy. Only tap water shall be used in the rocket, and the water shall be provided by the organizers. Water brought by the team shall not be allowed in the rockets.
  • The amount of water to be filled in the rocket body is left to the choice of the team.
  • The pressure inside the container (rocket body) before launch should not exceed 60 psi.
  • Launchers and pressure compressors will NOT be provided by the organizers.
  • The launcher to be constructed by the team should be fitted with an air compression device or pump for pressurizing the contents of the rocket body. A pressure-gauge having a minimum range of 0-100 psi to display the pressure of air in the water-rocket has to be attached to it too.
  • The rocket must be launched from a stationary position on a fixed launcher. (Slingshots, trebuchets, catapults, cannons, and all other forms of launch/ boost assists are forbidden). In other words, the internal pressure of the rocket must be the only source of energy for the rocket.
  • The rocket may or may not split into two or more parts only during the flight, in such cases the range of the farthest part will be considered.
  • The teams may bring as many rockets as they wish but it should comply with the rules given above.
  • The decision of Team NSSC will be final.


  • Team Size: A team for Lift-off can have a maximum of 4 members. However, they need not be from the same college/university/institution.
  • The rocket must have a variable launching angle capability.
  • Burst Testing: All rockets will be tested to a pressure of 60 psi before they can be allowed to enter the competition. Teams are therefore advised to test their rockets to a pressure of 60 psi beforehand and also bring substitute rockets with them.
  • If a team's rocket fails the Burst Test, ONLY ONE extra rocket shall be allowed to be burst test. If that rocket fails the burst test too, then no points will be awarded to the team.
  • Once a rocket passes the burst test, it shall be allowed only one attempt for launch.
  • Participants are allowed to use a multistage water rocket.
  • In case of multistage water rocket maximum of 2 litres water is allowed inside the rocket.
  • The rules are subject to change.
  • In case of disputes, the decision of team NSSC is final and binding.


  • The participants have to launch the rocket from the launching point and the rocket should land in the launch arena.
  • The launch arena will be a sector of the circle with the sector angle of 45� and the launch will take place from the centre of the circle.
  • The range of flight is the distance between the point of launch and the point of the first impact with the ground after launch.
  • In case of multi-stage water rocket range of flight will be calculated as the distance between the point of launch and impact of 2nd rocket with the ground.


    Round 1

  • Participants are scored primarily on the basis of the range of their flight. Greater the range, greater will be the points earned.
  • The rocket going out of the sector at an angle of 45 degrees will not be awarded any points.
  • Rocket landing inside a sector of angle 15 degrees will be given additional points corresponding to a distance of 25 meters.
  • No additional points will be awarded if the rocket lands on the border of the inner 15-degree sector.
  • Round 2

  • Top 16 teams of round 1 will advance to round 2.
  • The problem statement of round 2 of liftoff will be disclosed on the day of the event.


  • Top 3 teams will be awarded by Certificate of Excellence for the event.
  • Prize money worth 20,000 INR will be distributed to the teams.
  • The winning team has to complete the task, if they fail to complete the task then they will be not eligible for the certificate.
  • If all the participating teams fail to solve the problem statement then, only appreciation certificate(s) will be distributed to the teams demonstrating excellent performance.
