Hello WRA members !

I joined the water rocketeers in 2000 while looking for projects that will interest the children in my son's school. Working with young students was a challenge, it led to simple designs that 6 year old children can build and launch many times. The rocket design I use is the "Skewer Design" – easy to build, flies well and requires little work for the next launch.

See: http://www.h2o-rockets.com/SkewerDesign-v02.html

Then we looked for a simple method to measure rocket height with tangible evidence, this let to the "calibrated pictures" method. It is not fit for record claims, but most of us (me included) don't have a good recovery system so the first launch of a 69$ altimeter would also be the last one. With the "calibrated pictures" you can measure the height of a rocket with no on-board equipment and get a good estimate of it's performance.

Looking forward to share water recketry with all of you !

Hello fellow WRA2 member. Welcome to the forum and the WRA2!

This place is not really about records 100% of the time, there's hundreds of people here who just come here to learn and to share information. We enjoy the discussions here as much as the next team. Nice to have you here.
