====Summary====                   
{{$demo.summary}}



====Procedure====  
  - Cut a garden hose to about 15–30 cm in length.
  - Roll a sheet of card around the outside of the hose to form a rocket body, securing it with tape so it fits snugly but can slide off easily.
  - Seal the top of the rocket into a point with tape to make it air-tight.
  - Cut triangles of card and attach them to the bottom as fins; experiment with different shapes and sizes.
  - Remove the cap from a 2L pop bottle and tape the hose securely into the mouth with duct tape, ensuring an air-tight seal.
  - Place the rocket on the free end of the hose.
  - Position the launcher outdoors, making sure it is pointed safely away from others.
  - Stomp on the pop bottle to launch the rocket.
  - To relaunch, blow into the hose to re-inflate the bottle.

====Variations====
  * Purchase and use a commercially available stomp rocket
  * Investigate how the number, size, or shape of fins affects flight stability.
  * Test different materials for the rocket body (e.g., thinner paper vs. card).
  * Try shooting at a target for accuracy.
  * Experiment with different stomp strengths and compare flight distances.
  * Investigate how the angle of launch affects the distance covered, predict and test which angle launches the rocket the farthest.



====Safety Precautions====
  * Launch rockets only in an open outdoor area.
  * Always point rockets away from people and fragile objects.
  * Keep students at a safe distance during launches.
  * Supervise use of scissors when cutting hose or fins.




====Questions to Consider====
  * What force pushes the rocket upward? (The escaping air pushes downward, and by Newton’s Third Law the rocket is pushed upward.)
  * How do fins affect the rocket’s stability? (They help keep it flying straight rather than tumbling.)
  * What launch angle gives the greatest distance? (Close to 45°, assuming no major air resistance.)
  * How could you make the rocket go higher or farther? (Use stronger stomps, better air seals, or lighter rocket bodies.)
