How Do I Make A Water Rocket
A launch tube can have a significant effect on the apogee of a rocket. For those of you who prefer the "Presta" type valve stems, we will suggest some alternative methods you may use to connect those types of valves to the launcher as well, so don't despair. While a third the volume may be a good approximation, every particular rocket will have an optimal water fill based on its weight, drag coefficient, pressure, nozzle size etc. Slide the o-ring down the cpvc pipe until it reaches the bottom stop at the top of the 1/2" PVC pipe. About 12 inches for the launch tube (this will vary depending on your rocket length).
internal wave reflects from the other side of the rocket. Remove the label from the bottle first, so the tape sticks better; otherwise they rip off at speed.
Treat the fins like feet for the rocket. It would take a two-bottle rocket, with the egg well-cushioned in the middle. Rocket flies straight normally but veers off course at launch No or too short guide rail Increase the length of the guide rail(s). Water-proof markers are best - to launch you'll need to pour water into the bottom of the rocket, and may spill. Take the cap of your bottle and outline the size of the pen barrel onto the cap. If you would like your rocket to fly higher, here are some suggestions for flying higher.
Make sure that people around you are keeping their distance from the basketball water bottle.
Use grow a fin alignment jig. Fold a 9 inch piece of duct tape into a U shape with the sticky side out, place it into the bottle with the bottom of the U against the kitty litter, and press the sides of the U against the inside walls of the. Another update-you can tape the fins at a bit of an angle so the rocket spins, for better stability.
Balance internal components in the rocket. That is the theory. The fins should be as rigid as possible.
Ballast two-bottle rocket For a two-bottle rocket, I use clumping kitty litter in the top end. Decoration is also practical - it is a way stepping to occupy paneling early finishers when working with groups of kids :-) Launch I use one from m, I paid 50 in 2011. Fold each half in two the long way and cut again; fold in half the long way again, and trim off tabs to make straight sides. That sometimes loosened the kitty litter enough to break free at launch, showering anyone too close (that would be me) with wet kitty litter. 2 Gather baking soda and vinegar.
How can this be launched? Take a drill the size of the pen barrel and drill into the center of the cap. 9, connect the pen.

How to Make a Water Rocket The Art of Manliness
3 Combine your ingredients. This is a lot of work, a floor pump helps. Rocket will 'weathercock' into the wind if this is the cause. This method creates more of an explosion based rocket, so it can be a little dangerous. Uneven airflow over rocket due to protrusions such as camera housings, air flaps etc. Put it on straight!
Materials water bottle(s) - two-liter, not scratched. Start the cut with box cutter, and finish with a scissors (for a nice clean cut, so the bottles can be taped together cleanly and straight. The fins are attached near the bottom of the rocket, with the bottom of the fin tabs at the bottom of the straight sides of the firing chamber. The tabs are folded out and taped to the bottle using a half-strip of duct tape; you may need to adjust this to get the fins straight. This chemical reaction is the fuel for the rocket.
