Introduction: Origami Rocket

You can make a real, working rocket from a simple sheet of paper!

The heart of this is a traditional "water bomb" origami model.  There are already quite a few Instructables on making the water-bomb, so I simply present the steps as photos.

Turning it into a rocket, though...

The fuel I chose for this project was propane from my blowtorch.  It's a happy coincidence that a drinking straw fits down the central delivery tube of my blowtorch.  I cut a straw to a spike, and it became a perfect delivery system for injecting fuel into the water bomb through the inflation hole.

I blew in gas for a few seconds, laid the rocket on its side, then applied a match to the hole.

Woosh!

I normally fuel these with methane (natural gas) from my lab gas-taps, so a few rockets went up in flames while I got the fuel-air mix right...



An impressive feature of these rockets in lessons is their size - I can keep a handful in my pocket, inflating them as I need during the lesson, as we discuss the various factors that can influence the distance they scoot across the desk.

Er, if there are actual flames, something has gone wrong...

lol... doncha know?  That's the Redneck Way. ;-D

The fuel is supposed to explode - what kind of gas did you use?

There's your problem - you should have used a gas that won't react violently with the paper the rocket is made of.

You know, like the propane I mentioned in the text...

OK i just did this and for extra measure coated the inside of the paper with heat resistant paint. it didn't work and produced a lot of smoke. though next time i am going to use card stock.

i may try this project just for fun but i am wondering will i end up with some thing like this.

Er.... not quite...

Very neat working rocket...

I would like to know of any interesting failed projects.

Somewhere in the depths of my shed is a failed "Kelvin's Thunderstorm".

You should remake it into a non-failure and post it. Kelvin Thunderstorms are pretty cool I think at least I think so know after I Googled it

It's on my list.

However, my list currently has over 200 projects on it...

Hmm... Well sounds like a busy day

Goddard invented the *liquid* fuelled rocket...
