Research Question

What is the best type of nose cone to use on a water bottle rocket?

Experimental Procedure

  1. Assemble the rocket launcher according to the diagram. (glue all the joints together with pvc cement)
  2. Attach nose cones to 3 of the 4 bottles using hot glue.
  3. Make fins for the rockets by folding a 5” by 8” index card in half and then cutting it into the shape of a triangle.
  4. Repeat step 3 fifteen more times. (you will make a total of 16 fins)
  5.  Attach 4 fins evenly spaced to each rocket using scotch tape.
  6.  Fill 1 rocket with exactly half a liter of water.
  7.  Place the rocket on the launcher and using the bike pump, pump 20 psi of air.
  8.  Have someone stand by you with a stopwatch.
  9.  Release rocket by pulling string.
  10.  Record the time it takes the rocket to reach the ground.
  11.  Do steps 6-10 for each of the 4 rockets 30 times.
  12.  Record all the times in your composition book.
