Introduction: Ultimate Straw Rocket!

What is the "Ultimate Straw Rocket"?
Answer: A very easy to make rocket made from a drinking straw, and launched using air pressure.
Almost everyone will be able to make this, it does not require any hard-to-find items, but also can it be made in very little time. Therefore will the rockets themselves be very easy to mass produce.
They will fly HIGH up in the air, and then land on the ground, completely safe!

Okay let's get started!


Step 1: Gathering Materials

As first said, the items are very easy to get, and you probably already have them lying around your house.
You will need to print following document to continue, though:
Download this .doc!

The rest of the materials are descriped in the picture.

Step 2: Making the Rocket

Cut a 6cm piece of a straw.
Put a dot of hot glue in one end of the straw making sure it's air tight.

Step 3: Attaching Fins

Now cut out a pair of fins from the printed document.
Then fold and glue the fins together. Stippled lines means "fold backwards", whereas straight lines means the opposite.
You can use hot glue to glue the fins together, but I find that white glue (Elmer's glue or wood glue) works well.

Then glue the backside (the white side) and attach it around the straw, approximately 1-1.5 cm from the open end of the straw.

Step 4: Launch It!

The rocket is finished now! Wasn't that easy?
Now for launching it:
Insert it all the way down in the nozzle of the bike pump, and give the bike pump a good, fast pump! Now enjoy your small flying rockets...
I had my rockets to go as high as ~10 metres!
Don't forget goggles, you don't want the rocket in your, or everyone else's eyes.



Thanks to Peter Hald for inspiration.

The fin pattern document is no longer available. I tried searching on Google, but couldn't find a similar fin. Does anyone have a source? Thanks

I'm gonna make one that's a bit longer that includes a fire cracker for a warhead XD

Put a small hole with a needle for the fuse to com out of, light and launch, and watch the fireworks!!! >:D

I shot these with an air compressor at about 90 psi and they worked quite well

Epeoples made it! (author)Epeoples2008-11-09

an air compresser? wow, isn't that a little extreme? anyway, can the straw be longer? would it go higher?

author
reywolf made it! (author)reywolf2009-05-29

there are two major parts (with other little things) to a rocket: stability and thrust. to get a better stability make it longer. the more surface area the better stability. to get higher you need more force which means better aerodynamics. so longer doesn't usually mean higher. except for the fact that it can hold more air, and thus a higher psi and thus longer in this case does equal higher. if you want more detail on how to get stability and thrust message me. im not an expert but i do know a thing or two about physics.

you can put glue in the end to stop the air escaping

Your Average Guy made it! (author)2008-10-03

I made one and after about 5 shots it exploded with a satisfying *pop* Anyone reading this just use the weird head that comes with most pumps. (here in the U.S. that is) I shot my brother a few minutes ago.

author
eaoee made it! (author)2008-09-07

I'm going to file the glue on the end down to the shrpest point I can get, or add something sharp to it. should be fun! Nice simple tutorial, even I should be able to complete it!! (by the way that is a very big deal)
