how did you make the parachute
axe0fm 1 year ago
Parachute was made from a piece of round rip-stop nylon with a center hole. Strings were braided fishing line. Chemical reaction of baking soda, citric acid and water extended a syringe to lift the nose cone. Elastic band pulled the parachute out of the nose cone. Ken S.

Just wondering how so much water comes out of the bottle, is the nozzle small to allow a stronger and longer burst? I have a water rocket launcher, they are so fun!!!

This rocket used about 680 ml of 30% soapy water. Nozzle is small so that the energy is released over a longer period, otherwise it would go too fast and disintegrate. Thrust was about 17 pounds even with such a small nozzle throat, 0.136 inches diameter. Ken S.

The tubes supporting the ring fin are polystyrene, from the local hobby shop. KS
