i have become intrested in these things again however my success rate with these things sucks. i like the baking soda and vineger onem the best.i have some questions how much bs and vineger would i have to use to burst a 20 oz plastic bottle. i fill my my bottle like this i take the bs and pour it down the bottle and i take a ziplock bag and put it down there and pour vineger in it and put the caop on and shake for about 10seconds. but each time i do it it never bursts i resort to throwing it against the pavement to get any kind of noise, help i need some good messurements on how much to use. any help

Never hold one of those in your hand, becuase vinegar and baking soda reacts VERY fast, and if you get the right amount it would only take a few seconds to burst the bottle. I would go with a 1/2 cup of each if you really want to stay with vinegar and baking soda, but they set off much faster than dry ice bombs.

I use potassium permangate and glycrine. There is a flash and BOOM. Any other fuels in there will add nicely, almost like stars flying around.

^^ Aye, the kmno4 one is pretty good, but I prefer HCl/Aluminium Myself....

Hmmm, what are the legelites of pressure bombs? Other than mabye violating a noise ordince, are there any other laws that you could break making them in your backyard?

Ask Warweed.

canda laws and us laws are different.

The best way i have found to do it is to put 2-3 inches of BS in the bottle, then get a condom and drape the "rim" of the condom over the mouth of the bottle, so that most of the condom is inside the bottle. Then when you are ready slowly fill the condom with HCL (the reaction with Acetic Acid is too weak to provide the pressure requred to burst that kind of a bottle) The best acid to use is the Mutric Acid for cleaning pools (it's not pure HCL but it's dirt cheap and it does have a pH of "0" so it should work OK). Then just put the cap on TIGHT, over the condom, and throw the thing at somthing, hopfully a long way away, and the impact of the bottle hitting the ground will dislodge the condom spilling the HCL into the CHNaO3 (BS). This will most always rupture the bottle producing a sound louder than a shotgun, but only if the cap was on tight enouf not to burst first. And if it does not expload after 2-3 mins. DO NOT GO GET IT! If there are any duds, i shoot them with a pellet gun from a distance. These can be very dangerus if you don'tknow what you are doing.

My pressure bomb didn't work. All it made was a mess of HCl covered bull shit. I'm thinking the BS was the problem...

If you use vinegar and baking soda, how in the hell are you supposed to get the baking soda into the bottle fast enough to screw the cap on and then get away?

Or do you put the sodium carbonate in the bottle first and then add the vinegar?

i put the bs in the bottle then i put a bag inside of it with vineger and cap it and shake.

Did it create enough pressure to actually burst the bottle? If so, how long did it take?

What measurements did you use?

The best one I've done(not including dry ice) is toilet bowl cleaner(I use 'The Works') and Al. foil balls in a 20 oz bottle. If you stand the bottle on the bottom part, its louder than a rifle.(or it least it is for me). I tried it with a 32 oz bottle and stood it on bottom and it shot up like 15'. It was awesome.

Even with my largest pressure bomb (over a litre of HCl acid) it still took about 20 seconds before anything started 'reacting'. I've never had to wait anymore than about 40 seconds, but make sure you fill the bottle up with at least 1/4 of acid IMO.

For the aluminium, just rip up some foil and crunch it into littles balls so they can fit thorugh the neck, you'll genreally want the acid just covering the top of them.

Pressure bombs are great and easy to make, you can always fiddle around with chems - anything that releases a great deal of gas will generally work (dry ice etc).

I've never used a vingar/baking soda one myself, but kmno4/glycerin and HCl/Aluminium would be the best, both are pretty different though.

Some people ask me if the HCl acid shoots everywhere in the 'explosion', but I've never seen it go beyond two metres so its a fairly safe device (don't inhale the fumes though).

I've also found if you have ungodly amounts of reactants, you can actually make a fairly good smoke bomb from the HCl one.

Never do a pressure bomb in a crowded city or sometimes even suburban area, as they are *extremely* loud.

And of course, even though there is usually a good safety margin get rid of any pressure bomb as soon as you can.

HCl and aluminum create hydrogen gas correct? Anyway, what if I were to keep some kind of flame on the outside of the bottle or near it so when it burst it in turn creates a fireball. Would this work?

David, is that you?

No, look at the date

this may sound kewl but i forgot what hci is what is it.

HCL is hydrogen chloride, gas in pure form, in solution, hydrochloric acid.

the legalitiys include in canada is a Section 82 Sub 1 Sub C possestion of an unlaful explosive device with a maxium adult penalty of 2 years in jail or a $2000 dollar fine or both .. but that is maxium i had a very good lawyer and convinced the crown to lower the charges to mischief .. and was released on a conditional discharge .... but i was very lucky ...

thanks fellas, i get that hcl as muratic acid(sp) right is it pure, can i use it as is?

Yeah I wouldn't try to boil it down or anything.

Defently not !! that will release HCl vapours into the room and fuck your lungs pretty bad !! it hurts like a bitch

Aye, a whiff of that smells fucking horrible. Kinda like sea brine to me, but super strong.

You can trap the gas and make a balloon which you then ignite, that would work.

Static has done it, he said it just makes a WMOOF sound and shrivels the bottle.

I'll pick up some HCl and mabye try tonight.

Sodium Hydroxide and Aluminum makes hydrogen gas...

Hydrochloric acid and Aluminum makes water vapor and aluminum chloride ...

If you stretch a balloon over a container with NaOH + Al it puts H2 in the ablloon but also NaOH suspended in water vapor, and it will corrode holes in your balloon.

Please stop saying that.

2Al + 6HCl -> 2AlCl3 + 3H2

It most definately does create H2

yes warweed get your facts straight YOUR A MOD FOR GOD SAKE.

anyways why hasnt any mentioned the good old manganese dioxide pressure bomb. I was thinking of trying one with a table spoon of it and some 27% conc. H202

I dont think there should be any more discussion about pressure bombs on this board. Too many people have been caught and seriously punished becuase of them.

I wouldnt make one if someone gave me 500 dollars.

This is my opionon on them, and I believe there are easier, safer ways to get loud reports.

they found 2 pressure bombs outside a highschool in my area like last week. they had to bring in a fuckin bomb squad. their currently searching for finger prints on the bottle.

500 bux? hell ide do it. it seems the only people getting caught are doing them in public areas

Well, what i do to make hydrogen ballons (HCl and Al Foil) is i made a filter (bubble the gas through water) and then have a ballon over the bottle with the filter. I get H2, i know it. Water vapors don;t blow up, nor are they flammable. You gotta recheck your reaction Warweed.

i Dunno guys i still swear by

6HCl + 2Al + 6/2 02 --> 3H2O + 2AlCl3

but they say there it Hydrogen ... and i have yet to have this so maybe some one could clarify my chemistry

Apon Further consulting of a chemistry genius lol i got this reply

"12HCl + 4Al + 6 02 --> 6 H2O + 4AlCl3

had to double the quanitys of HCl and Al to get it to work with an even amount of O, and that resulted in having to double the quanitys of the product. There is no H2 product. Or you could do it anerobicly (no oxygen) and get

6HCl + 2Al -->2AlCl3 + 3H2 which is much simpler though if the goal is to produce H2 gas zinc or magnesium works far better than Al"

I have 2 pounds of zinc powder. Cool, so just the zinc and HCl will produce H2 anaerobically?

Don't waste zinc powder like that! Oh man, where the hell did you get it? I can't find zinc powder anywhere....

Hey third rail catch me online AIM deadsexygflavor. Or anyone for that matter.

Why do you want zinc powder? Negative X?

Trust me it isn't all that great plus it is extremely sensative to water and humidity I cannot stess this enough. I was makeing some and about 10 seconds after I took off the lid of my mixing conainer it spontaneously ignited. It didn't hurt me just scared the shit out of me. And trust me it wasn't even that humid out.

When did Pyrotek start carrying zinc powder? This rocks! Where's the credit card?!

Yeah, that's why UN says not to store it!

i've tried the hcl/al device and it worked well for me. is there anything that could be mixed with sulfuric acid to create enough pressure?
