Welcome to the Water Rocket Forum, sponsored by The Water Rocket Achievement World Record Association.

The largest, most sophisticated and ground breaking group supporting you, the serious water rocket flyer! Whether you are a beginner or an expert, the WRA2 has something for everyone.

A water rocket is a type of model rocket using water as its reaction mass. The pressure vessel (the engine of the rocket) is constructed from thin plastic or other non metallic materials (usually a used plastic soft drink bottle) weighing 1,500 grams or less. The water is forced out by compressed air. It is an example of Newton's third law of motion.

You want your huge photos deleted. That can be done.

You can open up the "Paint" accessory and load up the image. Then you hit <control> W or use the menu bar to pick "Stretch / Skew". You input a new size for the picture in percent. Enter 50% or something in the Horizontal and Vertical values and you'll see the picture resize on the screen. You can then "Save As" and pick a new name for the smaller image.

I usually pick sizes that are 25% smaller than my monitor screen so when I email them they fit inside a window and the recipient doesn't have to scroll to see it all.

Thanks Tim. Hows your 1000 foot rocket coming? We got SNOW here in MI. It sucks really bad! No test launching for a couple weeks.

Blah! it snowed all day Thursday and has been too cold to do anything outside all weekend. Mark and I made some progress on our electric deploy system instead, so it's been a productive weekend in spite of the crappy weather.
