Here's the Mercury-Redstone Water Bottle rocket I scratch-built from here: [link]

Our Physics class teacher gave us an awesome assignment: Build a water-bottle rocket.

A water-bottle rocket works like this:

A 2-liter bottle is filled halfway with water.

Placed on a special-built rig, a bicycle pump is used to pressurize the bottle to 100 psi.

Then, you let it fly! The pressurized air blows the water out, and sends the rocket flying!

In order for it to fly straight, it has to have fins, and some extra bottles on top to make it longer.

Here's the picture of me and my class, and what most look like: [link]

You have to do some tricks to caulk the fins on straight, and make sure they're big enough.

Parachutes?... Out of the question. You just fly it and crash it. My teacher has tried for many years to get parachutes to work, and has never succeeded... So when I heard about that, I thought: "challenge accepted!"

So here's my rocket, and its story.

This picture taken after the partial failure of launch, and sitting next to it are the blueprints it was initially conceived on.

Oh, how far it's come from being nothing more than an overly ambitious, wacked-out fanciful idea...
