Water Rocket CRASHES!!!
Over the last 7 years we've had plenty of opportunities to learn from our mistakes. To date around 1 in 10 of our launches results in some kind of off-nominal performance, so here is a small compilation of some of those valuable lessons: 00:22 - Need a recovery system 00:34 - What's stability? 00:41 - Don't put fins too far forward 00:45 - Don't launch near water 00:49 - Nozzle seals can partially block the nozzle 00:55 - Nozzle seals can partially block the nozzle 01:05 - NOAA doesn't always work 01:17 - You can re-inflate crushed bottles 01:21 - Flight computers need to be turned on 01:36 - Clothes lines chop rockets in half 01:47 - NOAA fails often 02:05 - Don't make fins too small 02:16 - Not all stagers release 02:30 - Staging when pointing down is not a good idea 02:46 - Rockets can bend during high acceleration 02:58 - Servo releasing doesn't guarantee an ejected chute 03:16 - Clustered rockets don't need a nozzle partially blocked by a seal 03:31 - Don't put in too much pressure 03:51 - Properly released parachutes can tangle 04:08 - Robinson couplings can weaken bottles and act as nozzles 04:24 - Pressuring vibration can cause early launch detection 04:31 - Don't deploy parachutes at high speed, without a strong shock cord 04:52 - Don't try to land with an unreleased stager 05:36 - Secure your nosecone properly 06:15 - Parachutes are useless when not deployed 06:30 - Don't over pressurise a rocket 06:53 - You CAN fold a rocket for better transportation back home 07:11 - Slow acceleration can fail to be detected as "a launch" 07:24 - Stuck nosecones don't help with recovery 07:57 - Airflow can be significant in pushing a parachute out 08:19 - Acceleration + pressure can cause a rocket to go boom mid flight.
