Andrew W.'s Hydro Rocket Page

Those were some rocket pictures that I like. The last picture is a Hydro Rocket. I included spirals because I like them.
This is a rocketry site that I like: http://www.deltavrocketry.com/

These are good rocket sites: http://www.sciencenetlinks.com/interactives/gravity.html, http://www.ohio4h.org/rockets/demorocket.html
This is a rocket game where you have to rescue ducks: http://www.coolmath-games.com/0-abducktion/index.html

The hydro rocket works because of pressure and water. Water is the fuel, and the pressure launches the rocket.
Different styles of rocket:
Glider Rocket, high
Open Parachute: Medium low to Medium high
Cone Swing: Very High
Nose Cone fall: Very High

Different Recovery Systems:
Parachute out: Good recovery
Parachute in: Medium to low recovery

Vinegar Rockets

Vinegar rockets are powered by chemical reactions. Vinegar, an acid, reacts with Alka Seltzer, a base, to perform a reaction that blasts the rocket upwards.
We built our rockets out of feathers, tape, straws, Popsicle sticks, and paper. We had a fuel cell, in which we would pour vinegar in when the rocket was upside down. Then we would take half of an Alka Seltzer tablet and put it in, and close the lid quickly and put the rocket right side up. After a few seconds, the rocket would blast upwards. My rocket went only about two feet up, probably because it had too much weight.
