paint 'bombs'

[An archist]

I don't know if anyone posted this before, but just to be sure, I thought I might better do it.
Everyone probably knows how to make regular paint bombs? Yes? Ok.
well, if you wnat to save yourself time: just make a habit of keeping your egg shells after you make them, pretty simple: you carefully make a tiny hole in one side of an egg, a bigger one in the other side. You blow out the content and voila! the eggshell is ready to hold paint. (seal off with candlewax)

what are you making the hole with?

I was thinking that but wouldn't it cause a crack along the entire side of the eggshell?

Only one way to find out.

That's a waste of food...I'd rather use a bottle or a lightbulb.

No it's not, that's the point: when you're making eggs: you blow out what's in the egg and you can still use it. Whereas bottles or lightbulbs are pollutant.

on one side you use a needle (tiny hole) the other side, you carefully use a knife, the hole should be big enough to get paint in. It's really quite easy, one egg takes about 20 seconds 30 at most.
The best way to get a lot of eggs is to keep all the eggshells, even when you don't have an action planned yet. Just save up!

And for vegetarians: you need to eat a lot of eggs ;)

[Ander]

Wait...so you're saying that the actual stuff (yolk?) inside the egg is used to eat?

[Global_Justice]

you can still use the egg for scrambled egg :D thats the best kind of egg anyway :lol:

[subcal]

You had me all excited, I was hoping to read that the mix rate for ANFO was 6% F by weight to A. Then to read in the method was that all good aspiring people blend with plastic in plastic then add a dollop of food colouring to ensure the mixture is even before packaging. :ph34r:

Vegans might take offence to the eggs.... :)

[Whitten]

Paintball paint grenades would be more effective.

[loveme4whoiam]

Aren't those plastic though? You'd have to chuck them pretty damn hard in order for them to shatter. That is, if you are talking about the big paintball containers you can buy as addition ammo thingies.

Smart idea though, especially, as you say, its very quick and cheap to make many of them. Have to be careful in transporting them though :unsure:

I dont mean the containers the paintballs come in, I mean real professionally made paint grenades. Such as this (http://www.specialopspaintball.com/shop/product_detail.asp?SKU=611+0009&CAT=114201) or this (http://www.specialopspaintball.com/shop/product_detail.asp?SKU=610+0001&CAT=114201)

[loveme4whoiam]

Oh right - smart :D Those things look cool, and surprisingly cheap too. Still, I could buy several dozen eggs for the same price, but then you lose the cool factor. Decisions, decisions!

[Sadena Meti]

As an alternative, use the "mortal shells" used in professional fireworks. Large thin plastic balls (2"-4" dia), central seam, hole for the fuse, in this case, for filling (seal with hot glue). Any solid impact, even against a fleshy target, and they will break in half. Fairly easy to purchase online. Also, they can be launched from water ballon launchers, though expect a few to break open and splatter yourself.

[subcal]

surely there would be more then one way to do this. We all seem to be looking at bladder filled, impact detonated devices.

What about an air burst? let gravity and inertia spread our seed of paint?

Rev-Stoic got me thinking of a range increasing device (not going to use the word mortar launcher... even though its linked to fire-works... oops I just did)

The british sf have used wall breeching munitions that are bladders filled with water fired from compressed air. Its man-portable so it should fit our role rather nicely

[Sadena Meti]

The only way to effect an air burst would be to have a thingermabob in the projectile. I.E. a thingermabob that we can't mention on this board. Preferably a cold thingermabob, because some paint is flamable.

Also, once you integrate a thingermabob into the projectile, even if the goal is benign (i.e. splattering paint on someone), the device becomes very illegal. In fact, as illegal if it wasn't benign. 6 - 12.5 years illegal (in my locale at least).

Additonally, in the eyes of the law, a thingermabob that uses compressed gas (i.e. a cold thingermabob) is as bad as one that uses things black and powdery (i.e. a hot thingermabob).

So not a good idea.

And we probably should end the discussion of thingermabobs here.

[subcal]

I was thinking a reducer of some sort, like a rubber band or an inertia limited device like a marbe suspended in the liquid to get the air burst.

Its a thingamabob free zone.

[Enragé]

nice one an archist, i'll be sure to remember that one

[loveme4whoiam]

Expanding on the rubber band-airburst thing, if you used the bladder-filled projectile could you not attach a length of cord to a band that is secured around the middle. When the projectile reachs a certain distance and obviously pulls the cord taut, the intertia of the paint inside would push on the solid band, thus splitting the bladder and creating a sort-of airburst effect. Then it would all depend on angle of launch to determine the spread.

[Sadena Meti]

Two problems.

One, if it is secured with a rubber band, weak enough to be pulled off, it probably won't survive the acceleration of launch.

Two, you would have to use something like fishing line in a mechanical spindle to prevent it from being tangled, which it probably would anyway. In theory, yes, in practice, they'd probably go off a few feet from you.

I was toying with the idea of securing with a rubberband and putting acetone on it to disolve it, but 1. it would probably disolve the ballon first, 2. you'd have to somehow time the very variable chemical reaction perfectly to figure out when you have three seconds before it bursts, so I ruled it out as silly.

I don't think ever in history has this much combined brain power been dedicated to ballons filled with paint :D

[Sadena Meti]

Had another idea. When you were a kid, did you ever play with water rockets? You know, fill a container with water, pump air into it, once the preasure gets too much it shoots off the stand... and the water sprinkles out of it?

Who says it has to be water?

Or, if it is water, put some perm. dye in it, like what they use in bank dye packs!

In addition to the pumping method, another method of launch is to add dry ice. Instant CO2 rocket. Just wear gloves.

Actually if you were to get your hands on that bank dye, you could just resort to water ballons. Though a rocket would be cool :D

[loveme4whoiam]

One, if it is secured with a rubber band, weak enough to be pulled off, it probably won't survive the acceleration of launch.
Hmm, suppose you are right there. Still, its an avenue worth exploring in our quest for the perfect paint bomb :D Perhaps gluing the band on, or not using a rubber band. Hmm... But you are definitely right, if this was ever tried out in practice the "researcher" would be covered in paint long before he covered anything else.

The bottle rocket idea wouldn't work, because all the water shoots out of the bottom when the pressure builds up. So all the paint (even if it was diluted enough) would just splatter all over your feet when you fired it, rather than over the target.

So what do we have so far then? The cool water balloon launcher someone mentioned and the eggs seem to be the best bet, but airburst still sounds better. We must continue cogitating comrades! :D

[Sadena Meti]

I've been thinking about the dry ice... not as propellant, but as a "detonator". Now, starting with just water as a medium, you take a balloon like thing (thicker probably), fill with water, drop in the dry ice, then seal and launch. It sails through the air, dry ice converting to CO2 + water vapor until it ruptures. Blam-Splat!

But we don't want water, we want paint. Or dye. The idea of using bank dye appeals to me. Paint 'em bright purple. And I think that can be mixed into water.

The other technical question is, if you put dry ice into paint, would it produce gas in the same way water would? If so, I think this is it. Heavy ballon, filled with paint, drop in dry ice, seal, launch.

It would take some time to perfect the technique, but if you used the same balloon, same amount of paint each time, same sized dry ice lozenge, the result should be very predictable, and timed. And even if it didn't rupture in flight, if you used a thick balloon, it would land, bounce, sit... then blam-splat!

All hinges on what happens to dry ice when you drop it in paint. And experimenting with oil vs latex. Too bad I already have plans for this weekend.

[Whitten]

Yes paint should have the same effect on the dry ice as water

[Sadena Meti]

Very interesting... I think this is do-able. I'm sure there are dozens of technical problems that would have to be ironed out, but it sounds... well, sound.

As I have no need for water balloon launched air burst paint bombs in the forseeable future, I'm not about to commit a month to research and development, but someone else might.

When's the next WTO meeting?

[RevSouth]

Wouldn't the paint for a paintball grenade be the vegetable oil base stuff? If so, it wouldn't be best to use those grenades. Also if your talking billboards a grenade type device probably wouldn't be the best choice.

Could you elaborate on your first point... I don't quite follow.

As to your second point, I'd say the overall discussion has been more aimed at "showering ranks of riot police with pink paint".

As for billboards, those are far better to deal with by using... um... "accelerants."

My apologies for not expanding on my point. Most paintball paints, correct me if I am wrong, are vegetable oil based, so that they are biodegradeable and washable to a degree. Paintball stains exposed to the elements generally fade faster than other paints. If you wanted to paint something in a more vandalizing manner, i.e. not the police, you may want something more permanent.

Sorry for not paying better attention. :wacko:

[subcal]

I am about to embark on some serious research and development and I will share it with you all. I am thinking of using EEP (elastic energy propelsion) as the launch won't be as violent.

After some serious thought and discussion on the air burst problem with comrades we have decided that a spool of twine anchored to the device would be the best method to stop and burst the launched bladder. Hopefully the inertia of the liquid in the bladder will be sufficent to burst it without the use of a multiplier such as a marble as the risk of it bursting in the launch / acceleration stage is probable.

The bladder material is what I percieve to be the biggest hurdle. It would be nice to think a common balloon or two would suffice but I seriously doubt it for the moment.

For the moment I am thinking of a prod / bow design to cock and store the elastic energy. A track to aim the device and place the projectile to run up (maybe on some form of trolley) and anchor the projectile on a running spool of twine fitted and tied to the track. Trigger will more then likely be a mechanism to lift the bow string from a recess in the track to allow it to pull itself forward.

Anyone see any problems in this design before I start investing time in it>?

[loveme4whoiam]

Ha ha, I knew the anchoring idea was a good way to go :D

I agree that the bladder material will be the biggest obstacle - the common balloon might be too thick and not burst upon pulling taut the twine, unless the velocity of the projectile was exceedingly fast. Might I suggest modelling balloons as a possible material - the ones I had to work with once (don't ask) were pretty thin but obviously not too thin, so they might be worth exploring.

Am I wrong in perceiving this bow design as something similar in design to a crossbow? Because if so there might be some legal issues with such a device. Still, lets not let that stand in the way of progress :D It would also probably be the best way for a single person to use, as the water balloon launcher requires either three people (two holding either end of the elastic, the third firing) or a fixed point from which to anchor the elastic.

Good luck with the R&D, let us know how you get on :D

[subcal]

yeah I hit that crossbow problem when I had a bending prod. Have now changed design to a set of spear gun rubbers and a trigger unit from one also. it will also make the design slimmer and easier to carry.

have welded the track up and have a running eye down the centre for the trolley to allign with. hardest part so far was sourcing some angle bar for free.

I wish it was as easy to build as the shield I have been working on!

A friend of mine built a trebuchet that was carved to hold 24 eggs at a time so we could launch them at the fash kids from our school playing football. It was incredibly easy.

well thus far its a $5 dollar build. The concept coming from the forum here somewhere. Its a converted stop sign (liked the colour and they are plentiful and perfect for the application)

I simply cut the sign into 3 sheets vertically, added a pop riveted piano hinge to both the joins (so it folds flat into a back pack or under a shirt) and have made a eye to place a solid bar (also from the sign at side of road) behind the joins horizontally to provide strength.

Handles at the moment are material strips that I place my arm through.

The solid bar is a trolley bar handle. I have to wait for a friend to come over to document the build step by step and then smash it to see how strong it is, so far its copped a severe beating for practise purposes. Expect to see a new thread in this forum once its all finished...

[piet11111]

why not just get a can of paint and put in some dry ice toss it to the pigs before it works its magic.

fuck why bother with paint if you can toss molotovs

[An archist]

Jup, but sometimes you just want to vandalise stuff without killing people, for example, you throw some paintbombs at a poster of a political party, because if you would use a molotov, there's a chance the building to which the poster is attached will burn down, killing innocent people.
