LEARN ABOUT THRUST! Design and build a stomp rocket. Use principles of thrust and aerodynamics to create a working air rocket.

  • PVC Pipe (8-15 in. long)
  • PVC Pipe (3-6 in. long)
  • PVC Connector (45 degrees)
  • Construction Paper
  • Empty Plastic Water Bottle 
  • Scotch Tape
  • Markers
  • Scissors

activity

  1. Using the longer PVC pipe to shape your rocket, wrap a piece of construction paper around the pipe to create the body of the rocket.
  2. Make sure the paper cylinder is tightly wrapped around the pipe and tape the end of the construction paper together to prevent the paper from unraveling.
  3. When the paper is taped, remove the PVC pipe from within the paper cylinder. The PVC pipe is only used to shape the paper cylinder.
  4. Close off one end of the cylinder using tape. It is important that this end is air tight. (Note: If end is not air tight, rocket will not fly.)
  5. Build a nose cone for the rocket. Use current rocket designs to help you. Attach the nose cone to the closed end of the paper cylinder.
  6. Attach fins to the open ended side of the rocket. Use current rocket designs to help you.
  7. Using the PVC connector, connect the long and short pieces of PVC to one another to create the launcher.
  8. On the long end of the PCV pipe, slip your rocket over the pipe opening. You should slip the rocket over the pipe to where the pipe is halfway into the rocket. (The fit should not be too tight nor too loose. Adjust if necessary.)
  9. On the short end of the PCV pipe, slip the empty water bottle over the pipe opening.
  10. Have someone step on the pipe connector to hold the launcher steady.
  11. Jump and/or stomp on the water bottle and watch your rocket fly!

When we think of space travel, one vehicle comes to mind: ROCKETS!

  • Rockets are a type of vehicle which uses thrust to move forward. Thrust is a principle of physics based on Newtons 3rd Law which states, "For every action, there is an equal, opposite reaction". When a rocket burns its fuel, exhaust gas is forced out from the rocket's nozzle. As the exhaust gas moves in one direction, an equal force is applied to the rocket in the opposite direction which creates the forward movement, Thrust. 
  • As rockets travel at very high speeds, rockets require enhanced aerodynamics to reduce air resistance and to provide stable flight. 
  • Today, rockets are used in many different applications which deal with military use and space travel.
