Dear all, Here is a movie with 150+ students engaging science ! http://www.youtube.com/watch?v=Tl-cWDmKCeUÂ Please "like" the video on YouTube to support us ...
I finally got to try my CO2 tank and regulator with rockets today. I had used it once to add air to a tire that was low, and it seemed to work, but it was very...
... That doesn't sound like it had much in it at all. Did they say it was full, or did you assume it was filled? Is it possible that there was a leak and it...
Well, since I gave them an empty tank and $26 in exchange for it, and it was about 10 lbs. heavier than my empty tank, I assumed it was full. One other...

Hi fellow Rocketeers Here are my latest launches from May. http://sites.google.com/site/greenrocketsil/home I am still looking for a simple & reliable...
Try this atatached file. The tutorial is in Portuguese, but it´s very simple. An example in youtube: http://www.youtube.com/watch?v=JR4rfpSpiZE&NR=1 Bolivar ...
Hello Rocketeers Had a great launching experience at the Hebrew University in Jerusaelm We did however we loose one to the trees :( Launch movie here...
WOW Impressive 6 L on the launcher. Far to heavy. snigger I need a parachute. I have bought the launchpad kit, very nice. Off the rocket goes into the yonder....
Hi guys, This is just a follow-up to the progress on this rocket. We finished repairing the rocket over the last 3 weeks and since we had to create a new front...
Congratulations! That is an amazing accomplishment. Sorry if I missed you saying somewhere before, but what do you think is the pressure limit for this rocket...
Thank you Jon and James :) Jon, we really don't know what the pressure limit is yet. During development we hydro tested a ~40mm long section of a tube made...
Hi George Fantastic rocket! In the video I can see that it doesn't spin too much, that means that the construction is almost perfect! Do you think that this...
Thanks Dario. That is a very good question, and I think is one that makes water rockets interesting. No one really knows how high they can go. With model pyro...
Did anyone think about a flying lauchpad? I mean something like an baloon-sustained platform that carries the lauchpad, rocket (and a driver? ;P), that allows...
Amazing. ________________________________ From: George <air.command@...> To: water-rockets@yahoogroups.com Sent: Sunday, July 1, 2012 9:41 PM Subject:...
That's looking good Mike. :) What is the manifold intended for? Multiple rockets? I was curious, what is the adjustable pressure regulator you are using there?...
Manifold can be used for multi-bottle first stage boosters, or for multiple launches, like for scouts. The scouting events have so many launches and the...

I found it time consuming trying to line up the cable ties. Mike fit them in with rubber bands first, then tape, then clamp, then glue. :] Ralph On Mon, Jul...
Thanks for the comment Ralph. There are several ways to mount cable ties. I would like to have a custom molded nylon cable tie. Too expensive. I really...
After having some difficulty getting much CO2 out of the tank I got from a local supplier, I exchanged the tank at a different supplier. I usually fly at the...
A group that worked with kids in elementary schools doing science activities were shooting air only tethered rockets along the ground. The kids were having...
Hi, I just did a whole week of rocket launching with a home made launcher, well they all are! I used gaffer tape and stuck the cable ties to it, both sides,...

I just saw this on TV this evening. The bottles are installed as skylights in roofs in the Philippines. http://isanglitrongliwanag.org/...
This technique has been used in poor communities in rural Brazil. It was developed by a Brazilian and is very easy to do. I've seen personally this use and...
