Water Rocket Boosted Glider Experiment.

We recently discovered a way to easily adapt our Radial Parachute Recovery System so that it can be used to release a payload module carried along the side of the Water Rocket Airframe. Our first thought was to use this as a way to take a Paper Glider to a very high altitude, and then release it.
We improved further on this concept when we realized that a rubber band could be used to forcefully fire the Paper Glider away from the Water Rocket when it is released.
We took this concept and mocked it up and performed a number of ground tests on it to see how well it would work, before we did an actual test flight. With a number of really promising tests conducted, we then decided to perform a test flight.
We added several cameras to the rocket so we could see the plane from different angles, and with any luck some dramatic footage of the plane in flight. Then we armed the system and prepared for launch.
In this video, we show the concept in more detail, and then we want to hear your opinion. Do you think it will Fail or Fly? Post your ideas in the comments section of this video, and we may use your comments in the results video, which will be published at the end of the week.
Get your comments in now, and let us know. Will it Fail or Fly!

How to design a competition Water Rocket

Our team was recently asked to assist some  students participating in a water rocket distance competition held by their school. We had never done any experiments in achieving maximum distance, so we were excited by the prospect of applying our experience in setting world records for altitude, as well as the chance to work with students in the STEM field.
We have published the first episode of our documentary series that covers our experience in this project. In this introductory episode, we jump right into analysis of the competition rules and our thoughts on designing the perfect water rocket for this competition.
The video begins with a history of our involvement in the competition, and how we became involved, and then outlines all of the rules for the competition which we had to comply with. The video concludes with a rough design for the ideal rocket, and a test plan for the design which will fine tune the rocket to maximize the performance.
Check out the video, and let us know what you think in the comments section of the video.

Free 3D Printable Soda Bottle Adapters

Many people have discovered that 2 liter soda bottles can be used to store compressed air and used in places where "canned air" is typically used. Dusting electronics and airbrushing are just some of the uses people have used homemade soda bottle air tanks for. Some of the more inventive people out there have created arrays of soda bottles to increase their tank capacity. Some of these people have even realized that they can increase the volume of their individual air tanks by joining multiple bottles together using our bottle splicing technique.
The usual method for making an air tank involves drilling holes in the bottle caps and then attaching a rubber hose fitting to the hole. This technique is time consuming and can leak air. Fortunately, people wishing to find a better way to do this have another option: the U.S. Water Rockets Soda Bottle to 3/8" NPT Pipe Adapter!
These adapters were created so that we could more easily pressure test our water rockets or for burst testing of bottles, and we still use them for this purpose. But these adapters are a great solution for making a soda bottle compressed air tank farm! You can use them for either of these purposes, and probably a lot more functions that we have not even thought of!
The files and instructions are available for download on our Thingiverse page. Enjoy!
