Introduction: Homemade Bottle Rockets
- Make sure to wear the proper protective gear such as some kind of glasses for eye protection, safety glasses would be best .....
- gloves help as well so you don't burn yourself
I tried embedding it but alas, photo bucket is lame. so you get a crappy long link ....YAY

PS. if you like it ....rate it up .....don't flake !
Step 1: What You Will Need
2.A Hammer
3. a small bit of fuse
4.a small mixing bowl
5.A mortar and pestle
6.needle nose pliers
7. duct or scotch tape
8. wooden skewers
9.A Pencil
10. A nail
11. Black Powder
12.kitty litter
- Pictures of these will be listed in order below
Step 2: Begin Rolling the Tube
Fold your post it in half horizontally sticky side up so the sticky part bonds with the non-sticky part
And Begin rolling the tube
Step 3: Tape the Tube
Using scotch tape preferably, tape the tube tightly on the pencil
Step 4: Kitty Litter Grind Up
Grind your kitty litter using the mortar and pestle
Note: this is sometimes very difficult
Step 5: Pour the Litter
Then,put the pencil in after to litter
Starting slowly, pound the pencil into the tube compressing the kitty litter
- The reason Kitty Litter is used is because it is almost 100% Bentonite clay which is the same thing used in model rockets (the sealant)
Step 6: Add the Black Powder
Follow the Litter with the Black Powder being sure to compact it thoroughly.
Step 7: MakeYour Nossel
Taking the hammer and nail .....or better yet a drill bit in a drill.... CAREFULLY tap the nail into the top layer of litter all the way through to the black powder(this is the nossel)
Ps the smaller the hole, the more propulsion. But with a better chance of it exploding on ignnition
Step 8: FUSETASTIC
Take a bit of fuse and cut it with the needle nose pliers About 2" will do fine
bend the last bit of the fuse about an eighth of an inch onto itself.
Step 9: Its Beginning to Look Alot Like *Rockets*
Insert fuse into hole made by the nail ....if needed you can also put a small ball of paper in the hole to hold it in but mine usually stay fine
Step 10: Scewer Galor !
Get your skewers. For this size of rocket the skewers were too big so i cut them
Step 11: Coming Along
Using more scotch tape or in my case ductape, tape the skewer onto the rocket
Step 12: AND BAM....YOUR DONE
If there are any questions please, comment, and i will do my best to answer them
Oh I almost forgot, please use these responsibly. you never know what could happen.
Also check the local laws in your area or zip code, to make sure bottle rockets are legal
- One Last Note.... If your first bottle rocket does not shoot as planned don't give up ....it may be that its too heavy or that you nossle is just the wrong size.

where did you get the black powder? Can u make it?
You can find tutorials on line the teach you how to make black powder. All it is is charchaol, suffer, and potassium nitrate.
Charchaol, sulfur, and potassium nitrate.
sweet i just have a quick question is black powder just gun powder like out of bullets??? and does the skewer go flying with the rocket wen it lights
And yes, the skewer goes up with it.
black powder is "old school" and was used in muzzle loading riffles(think lewis and clark). the gun powder in new age ammo is smokeless and less explosive but burns quicker building up gases to propel the projectile to its target. bottom line: they are two different things.
technicaly, smokeless powder doesnt explode at all. just burns extremely rapidly. much faster than blackpowder in fact. however, the pressure and gasses created would burst the rocket well before it even started to move, so dont try it. not good for rockets. good for mini paper pipebombs. (and by default getting in trouble with the police in most places...)
How did you know that the nail would be a big enough nozzle for the right amount of thrust for the rocket, without detonating the rocket or being to little thrust?
Thnx.

guess work and multiple tries, i'd think. provided you can get your hands on real blackpowder (i doubt pyrodex would work..but maybe) these are cheap enough to build. so a few test runs shouldnt be hard. just get away before they go off. to be safe.
what exactly does the litter do?
