Frequently Asked Questions
  • How do I attach a parachute to my rocket?
    See the Recovery Guide for many ideas how to make your rocket come back safely.
  • How much water should I put in my rocket?
    This will depend on your rocket, but generally 1/3 is close enough to optimum. You can use a simulator to figure out the optimal amount of water to use.
  • How much pressure can a 2L bottle hold?
    This will vary from bottle to bottle and you will need to do pressure tests for each particular bottle, but thin walled 2L bottles can hold around 120psi.
