Just recently I made a Pneumatic Pvc Airgun. It works great but, I wanted more power out of it. So I thought I should make better bullets out of something reasonably cheap. This is what I came up with.
These don't shatter easily and work very well if they are shot out of an airgun. Plus these will decompose as oposed to batteries and other metal bullets which will take a hundred or so years to. So be eco friendly and make these bullets. Please rate it if you like this instructable.

Note: These are only done for eco friendly bullets.
These bullets might go through cardboard But these don't have enough weight
to do real damage. However I will soon post an Instructable on Way better bullets Who win in Weight, Accuracy, Distance, Durabiltiy and Destruction power. I'm talking about heavy weight champions.

Note: New even better bullets at https://www.instructables.com/id/Long-Distance-Bullets

Step 1: Materials

Hair Gel,
Pvc Piping (same size as your barrel),
Plaster of Paris,
and a bowl of water(about 3 Tablespoons)
Plus some Tape, sand paper,
Concrete ground,some tinfoil,
and a saw (possible a sharp knife)

Step 2: Make the Plaster and Prepare the Mold

Make the Plaster
First put 3 tablespoons of water into the Bowl, then add
two tablespoons of plaster of paris. Stir it around until the plaster is dissolved. add water or plaster to it make sure it will run but is still thick.

Prepare the Mold
Grab the Pvc pipe, the chopstick, and the hair gel. First scoop some gel up with the chopstick and put it in the pipe, swirl it around until the inside of the pipe is covered in gel. Now tape
the end of the pipe nicely.

Step 3: Fill It Up

Grap the plaster and start spooning it into the tube. Once it is full put it in a vice(if you don't have a vice make a base out of tin foil). now wait for about 45 minutes to a hour for it to dry.
(if you don't it will fall apart when you push it out).

Step 4: Shaping

Push the dried plaster out of the pipe, it should come out easily if you geled it nicely. Then cut it to size with the saw 1 inch sizes are great. Now useing the concrete sharpen the ends as much as you like (you may have to sand it to fit into the barrel,

Step 5: The Last Step......

Now depending on wether you want bullets that are tough as nails or Bullets that shatter on the target and leave a white mark.
Shatter Bullets
Grap the bullets and leave them out to dry for about 1 to 2 days. Or if you wan't to use them right now grill them in the oven as high as it will go on the heat gauge for about 10 to 15 minutes. On the other hand you can not waste power and do what I did which was put them in the fire using a custom-made tin foil bullet holder. These are fun on targets not very good at shooting throught stuff though.

Hard Bullets
Leave them out in the sun for 15 to 20 minutes. The bullets should be quite hard but, not quite dry and your done. These work well a shooting through targets and don't shatter as easly as the Shatter Bullets.

Have fun And remeber to be safe
<p>i m 13 ill just make them with liquid metal </p>

Gr8 Instructable. Has any one thought of using ice bullets ? I started using them but it caused my barrel to rust =( . have you thought about placing a nail or a bolt in it to give it a bit more weight ? <br/>
Hehe, put an LED throwie in a Polymorph round to make tracers. Would vaseline work better than the hair gel??? Also you could probably make a wooden stand for the pipe & have a centered hole to hold that nail or a large sewing needle.
Is polymorph expensive where your at? Because over here (New Zealand) it costs about ten dollars per two hundred grams!
tracers would be mean probably yes
Tracers have phosporous on the tip that ignites from AIR&nbsp;FRICTION.This means that the bullet has to be going FAST (as in, faster than 1200fps,or faster than the speed of sound) so most air cannons wouldprobably not be able to use tracers....or atleast, ignite tracers.
whats polymorph?
it would be more fun ( yet more dangerous ) to use actual phosphorous to make tracers.
thanks. yes i have thought of that and it would work well as long as its shot out of a pvc gun. puting a nail in would be hard because balanceing woulbd be hard good ideas mattrox
if the plaster is thick enough it should stay in place... shouldent it
balaning would no be that hard im just abit laz :p
If you used single bullet molds it wont be that hard to find the middle. Just to prove you wrong i will attempt this dangerous task =) ill post pics when i have the time <br/><br/>
how do u make those metal bullets with the tail?

Hey. These bullets seem pretty good there on my A-list things to do list this summer holidays.. Along with the rifle itself. Was just wondering whats the chop stick for? Is it to push the plaster of paris out of the mold?
Oh, haha I should have read the next step first before posting that comment above. So I take it that then hair gel works as a <span>lubricant to get the plaster of paris out yeah?&nbsp;</span>
you can use minola or baby oil instead of hair gel (mas mura) and you can use white portland cement (may nabibili sa hardware ng 1/2 kilo bag)
you know.. you could add baking soda into the mixture.... and have air bubbles in it....... Load into a turkey baster and squeeze.
If you really want to be ECO about this, use Clay to build the body, and add a seed inside (no heat treatment) Think of it like a &quot;Seed Bomb&quot;
i was toying with the idea of igniting the phospherous and decided that i was goin to make one with a capacitor and a pit of my special conductive lub in a small glass container that will break splatting the tip with the coductive stuff and connecting the capacitor tips causing current to go through and light the phosphurous soz bought bad spelling
you could use filler asweel instead of plaster
what do you mean?
What is "filler asweel"?????
filler is a hole filler it sets very hard and i spelt aswell wrong
filler could mean any type of filler. could you next time be more specific
sorry but im only `13
You could use auto body filler...bondo and bondo sets so hard it'll go through a frozen turkey if you have the velocity. ;) Bondo is hard when set and here's a hint with bondo (because I was a body man for years) The more red stuff (can't think of th name! Catalyst! Anyway..the more catalyst you use the softer your mixture will set, but using just a tiny amount of *hardener (THAT'S THE WORD!) will make your mixture hard as rock! Use sandpaper and an elecrric sander maybe a belt sander to shape them and you won't have to worry about nuts n bolts..just coat your mold with wax so the bondo doesn't stick to the mold and you'll be ready to go to war!
well any filler such as poly filler ,diy filler,putty filler anything
ha richt now where it live its 9.56Pm
If you're going to go through the whole process of firing them then why not use ceramic mud? (I have a ceramics kiln handy by the way, but don't ask me to make your bullets) Cermics mud will take heat, but might explode of it's to thick so be careful when firing in heat... Plaster of paris in comparison is like using cotton balls as opposed to uranium tipped projectiles. Ceramics mud is cheap too.. just check in the phone book for any ceramics supply house..plus you can even have custom molds made fairly cheap. Just a suggestion. ;)
if you add lead or steel shot to the mix and shoot them out at a very high velocity they are like tiny frag grenades, but stay very far away from the target unless you dont wanna keep your sight city boy
can you cut the bullet with a hand saw
which one?
after you make the stick of plaster of paris when you cut the to size
Yes, it is actually very easy to cut.
I am going to make mold for these. It you have a mold you can put some lead shot near the front to weight it better.
They look like tampons.
Really cool good job!
poop a loop a ding dong I am putting this one on one o my instructable Is that okay?
hula hoop and a ching chong this goes against section b of the instructables handbook, look it for yourself or I'll sue you!!!!!!!!!!!!!!!!! na lol thatill be fine mattrox
thanks abunch cook a look a ding dong laki laki ching chong
wasa plasura camp canesa and i goota hunch dat king kong lika playn ping pong
this is fun
yes id hav to agree buy the way would you like a bun
