Advice

  • Add soap to increase the time in the air and speed.
  • The smaller the nozzle of the rocket, the less resistance to take off and more stability in flight there will be. A larger nozzle, on the other hand, will allow the water to escape faster, allowing the rocket to go higher at faster speed, but remember that it will lose water more quickly.

Warnings

  • Stay away from the rocket while pumping the air and immediately after.
  • Don't pump too much air into the bottle.
  • Handle with care.
