Introduction: Water Rocket Challenge (for Instructable Members!)

About: I like to make instructables which are fun to build or make. I'm interested in bikes, science and rowing. send me a message if you have any questions.

BEFORE YOU READ, THE CONTEST HAS FINISHED.

In memory with the 40th anniversary of the Apollo missions

I want you.....Instructable members... and I to create Instructables so i scaled maned mission to mars with water rockets is possible for me to make.

If you contribute you will have and get all the things below:

your name will be on the side of the rocket
you will be given video footage of the challenge and a certificate send by email.
your name will be in the credits of the movie made
and you will have the honour that you have contributed to this project

Of course were NOT going to mars and its not about the moon but a water rocket lem (Lunar Excursion Module)would be a bit hard

I will show you what i am hoping to do in the next few steps

Step 1: Launch

The first stage is to launch a rocket (of Course)...

But not just a normal water rocket a scale model of the delta II.

The picture I made will explain

If you have any ideas for this please leave a comment on the intro. If you have a rocket that could do a task described in the picture like i do please leave a comment or if you want to contribute to the competition make an Instructable on it. and leave a link to it on the into.

If you instructable is used on the challenge your name will be on the side of the rocket

Step 2: Payload Separation

The next bit of the challenge is to create a mechanism to separate a payload from the rocket

The picture explains

Please contribute to this challenge...

for those who contribute will be given video footage of the challenge and a certificate send by email.

It will also be a fun thing to do!

Step 3: Re Entry and Delayed Parachutes

For this bit of the challenge I need the payload to drop to earth from apogee for about 1-2 second before deploying the parachute.

I want this to happen because it will be a bit of recreation from the mars rover re-entry.

Further more in the movie created your name will be in the credits.

Step 4: Landing!

For this part of the Challenge I need away of landing lego people safely on the ground with out breaking there little plastic bones. or the payload for that matter.

Instructables and comments entered to this challenge must NOT be stupid out unable to build
reverse water rocket thrusters could be an option for me as long as there not stupid or unable to build

Step 5: Docking With Other Vehicles

Don't worry I have got this sorted out i just thought i would tell you...

Its basically a the rc car docking (air tightly) with the space pad to get back home

Step 6: Bye Mars :( .....well Earth

For this part of the challenge I only need a design for a rocket to blast of from mars....don't worry it doesn't need to fit in the payload, it just happened to be on mars/earth.

Step 7: Video

Here is the video of the challange (water rocket launch)

If the video doesn't play please tell me as i can sort out a different format of the video for you so you can run it

The video has been shortend for viewing

Step 8: The End

Please leave your comments on the intro and please contribute to this

the entries entered will no longer be accepted from the 25th august 2009

    i know how you could have a 'bracing system'.

    ok, you have two bottles, one smaller, connected by elastic bands., which are taught when normal, but take the shock off impacts ect

    oh, wait, nevermind....two years late....oops

    i did a project on water rocket..made the model and mathematical formulations and simulation using matlab...and i did experiments too with different amount of water and averying pressure...it was superb ...any chance i can contribute here...so that i can get certificate or something :)

    The contest has ended. I will probably have the certificates and video to you by early to mid September

    Any videos of the flights available yet?

    Yes, on step seven... I will hope to get an youtube acount in the near future so I can post a lot more there. Thanks for your website, its brilliant. I would also like to thank you for the polaron' series of rockets.. which i have begun to make... on my other instructable 'professional water rocket guide'.

    Thanks

    You have uploaded a Windows Movie Maker project instead of an actual video file. I can't view it because the project is looking for the original files. Other than that, awesome project!

    Ah... but that's the thing. When is the deadline? Idk how soon I will be able to work on this.

    I deeply sorry but your email doesn't seem to work? It has worked with the other contributers but there was a failure with yours. Is it that you email provider can't take attachments? thanks Oscar

    o.O? I don't know.... I use yahoo. I use attachments all the time... which email did I give you? (PM me, don't reply as a comment so people can't see my email)

    why dont u just go out and BUY a rocket much more eaiser and less trouble to build and there are ones with payloads that u can put stuff in.

    3 replies

    Because the is instructables were you make things plus it's probaky cheaper to make a water rocket and i dought the rockets that you buy are water rockets

    user

    yea but arn't u a pyromaniac haha no but seriously it only like 20 dollars for a rocketthat does wat ur asking for.

    dude ur not getting the point. the point of doing all of this is the fun of building and launching it. not buying one in the store.
