Picture of 10 Minute Rocket
This instructable will teach you how to build a simple, ultra light rocket from household items (and of course a rocket engine)
Here's the supply list:
- 1 tube of superglue
- 1 roll of tinfoil
- 1 straw big enough to fit around your launch rod
- 1 deck of playing cards that you don't mind parting with
- 1 C rocket engine
- several rocket engine detonators + plugs
- 1 electronic detonator (and necessary cables)

WARNING: This is totally dangerous. I didn't die, but you might. It is NOT MY FAULT if you hurt yourself following these instructions.

Step 1: Building Yourself Some Fins

Picture of Building Yourself Some Fins
The fins themselves are pretty simple, the difficult part is positioning them evenly around the rocket. To make a fin, first you'll need to fold a playing card in half hamburger style. Take your superglue and seal the folded halves together, like a sandwich. Glue is going to ooze out the sides and get all over your fingers, but just suck it up and take it like a man. Make two of these sandwiches and let the glue completely dry.

Now you can need to do a little bit of measuring, but nothing too complicated. Take one of the folded cards and put it perpendicular to the other, forming an L. Mark off the edge and cut it away so you're left with one square-ish shape. Repeat with the other folded card and, if you've done everything correctly thus far you should be left with two pseudo-squares.

Take these faux-squares and cut diagonally across from the curved corner to the corner directly opposite. You should now have four fin shapes, congratulations. Now onto the difficult part, attaching them.

This looks like a neat project to try out with my son.

cool rockets.are its works?
Well gee I just read all of ur comments and i think that i would learn less in a beginning physics class!

Great instructable. I've thought about doing this in the past and just haven't taken the time. Clever idea for the nose cone. If you backed each fin up a little then they could help support each other(see diagram). The only problem with a rocket like this is if it maintains a parabolic trajectory towards the ground rather then just tumble because if this happens then it will continue to gain momentum as if falls and can do considerable damage. Hopefully when the ejection charge blows it will blow the nose cone off causing it to tumble rather then follow a parabolic trajectory.

Hello (zach),
I loved the instructable, and it reminded me of rocket I made last summer. By made I mean that I found as many engines as I could, chad staged them, and stuck fins on 'em. Attached is a picture. It flew. Mostly.

LOL... Did this with a D engine. We glued a kabob stick to it so it looked just like a bottle rocket. Fun stuff, still have all our fingers !
and eyes?
Yes but i doubt he can hear anymore lol
Yep, I can still hear, although all of the industrial tools I've used have knocked my hearing out in a few places.
 Unfortunately, I'm blind in both ears and deaf in both eyes, so...

Yep, both eyes
Gluing a pointy stick to an already unstable rocket is about the only thing you could do that is more stupid then actually making it in the first place.
The stick makes it stable.
Cast the first stone...

I saw somebody launch a multi-stage one of these! Just loosely tape a booster engine (something like a B6-0) to a regular engine (say, a B6-5), put a cone-shaped thing on top, and tape the fins to the upper engine, but so that they extend down past the lower one a bit. WHen he launched it, it went up for a ways, we saw the second stage ignite, and then… it just disappeared into the sky.
Is the booster engine on top, or on the bottom?
That's the most awesome thing I've read all day.

u get a three good, but I extremely dislike the thought that i could kill my self... but I'd be happy what a hell of a way to die in your own amazing explosion dreaming of bigger ones.... im not emo I just like explosions and you may need to put a little more thought into the disclaimer, cuz it will probably not help you any... good one!
No, it wouldn't explode, the rocket will probably just fall over, crack your rib if it hits you, and probably make you go to da hospital. If it hits your nuts then you can be just like Justin Bieber, with his girly voice. Stoopid can drive says if we get the most cans in the Tri-State region he comes to give our school concert.
lol....that'd still hurt though
But then you'd be able to say, "I've been hit in the chest with a rocket" And Girls would be like, "Oh, wow, he's tough. Or an idiot." It depends, girls are weird.
Good point.
the only way i could see this killing u is if u lit it and then stuck it up anyway, its that or shoving it down ur throat and then igniting it. (tho there wouldnt be enough oxygen for it to stay lit)
"(tho there wouldnt be enough oxygen for it to stay lit)" Rockets don't need outside oxygen, they have the fuel and oxidizer both in the mixture. That's why we can use rockets in space. :)
im pretty sure they dont use rockets much in space, most of the time its just compressed air jets
Compressed air wouldn't work in space because... There's no air in space! The gas that was rushing out wouldn't work cause there's nothing for it to push against. They use rocket engines in space. Basically they have fuel and an oxidizer. The oxidizer provides the oxygen and the burning oxidizer and fuel provides the thrust.

Compressed air would still work!

The physics behind rockets is that "mass" be it air or other molecules. are exhausted from the nozzle. "Equal and opposite reaction"

The only problem with compressed air is that to achieve a sufficient mass flow rate the volume and pressure would be HUGE!!

Compressed air works exactly the same way that rockets in space work. You don't have to "push against something". All you have to do is throw something off of the back really fast and for every action, you get a reaction.
newtons law " for ever action there is a equal and opposite reaction"
True, but that law was made on Earth. I'm not sure if it would apply to space.
clazman dla8883 years ago
Now, I've heard everything. Please take a physics class!!!!!!!!
Newtons laws apply everywhere, even space.  :)
They don't apply at the quantum level.  :)
and on the quantum level you do not exist untill I observe you, which since i have not done, renders your argument invalid
I love literalists. :D
literallists like you but dont think they know you well enough to say they love you ;)
I just realized how bad my spelling is xD
I did not know that. I thought that gravity affected them a lot, but it's been awhile since I looked at Newton.
