My friend Brian has been going nuts with bottle rockets. He's part of the local CAP (Civil Air Patrol) and borrowed the launcher to show the cadets and use as a model for building his own launchers. Meanwhile the cadets are all busy fabricating a wide variety of rockets. I think there is a mass launch date planned in the next couple of weeks, I will be sure to share photos and movies.
Brian, ever the creative tinkerer, decided to build some multi-bottle and even multi-stage bottle rockets. The photo shows his first multi-bottle rocket. It may be hard to tell from the picture but that is one contiguous air cavity, even the caps connecting the bottle necks are hollow so air can flow between chambers.
BTW, the rocket and launcher is perched on a classic Yamaha SK30 synth he's been cleaning up to sell. Drop me a note if you are interested in it.
