/sci/ - Science & Math

That's not science. That's three dumbassed kids in the woods playing with fire.

yes, but we need science to make the fire as big as possible

Sugar and potassium nitrate, also known as rocket candy, is a fun mix. It was a primitive rocket fuel however it is really inefficient because it produces to many solids.

It does work well as a simple smoke bomb. The ingredients are easy to find (potassium nitrates common name is saltpeter, a common preservative)

The reaction is also really easy to work out if youve taken basic chemistry. You can use your stoichiometry to find out the correct mass ratios. There are also alot of different ways to mix it.

All in all its a good intro into energetic materials and will teach you alot of the basics, especially safety.

sounds great.

Any tips on napalm too?

Napalm is just jellied gasoline. All you need is some kind of polymer that will dissolve in gasoline. Styrofoam peanuts are the classic good-ole boy version. Id recommend mixing in some detergent and some diesel as well though. Detergent will help the spread-ability and diesel will keep it burning longer(small small amouts...like not more that 4% of each). Look up molotov cocktail recipies for some more ideas.

Be careful of the fumes, uber carciogenic. And under no circumstances get some on your skin or anything you care about.

Isn't asking for directions on how to make explosives highly illegal?

>>5858562

No.

Maybe in your country comrade. I also feel that its key to point out that none of these are explosive. Just incendiary.

Alot of us have gone through this phase, or at least I know that my friends and I have. The information is out there, however most of it (anarchist cookbook and the like) doesn't focus on safety instructions. I feel a responsibility to keep OP from blowin his hand off or worse.

country dependant,
also only if you make it

>>5858570
yes, thanks a lot.
And indeed, its perhaps childish...
We will also try making bronze, we know we need to build a special kind of oven, but how can we make it hot enough? I found some information about kingswater...?

mix styrofoam into gasoline

makes a jelly that when lit burns like crazy and basically waterproof gotta smother that shit with dirt. learned that in autoshop.

Curiosity is never childish.

Who knows, maybe you'll go on to become a materials science bamf. Check out New Mexico Tech if you're stateside. The College has the largest non-military explosive range on the continent and arguably the best energetic materials program as well. Campus is constantly rocked by detonations from research activities all day long.

>We are totally new in this kind of stuff
Mix KNO3, S and charcoal = 70:10:20. Yey, you've now got 13-year-old-kids gunpowder. Ignite several gramms and look how it burns.

The trick to founding isnt neccesarily the heat of the flame: its keeping it insulated. Make a small oven out of firebrick and high temperature fiberglass. Ordinary materials will transfer the heat of your source out of the overn to fast for your crucible to heat the metal up.

Butane in your bic lighter will burn at 3500*F given the right air mix. Most of the heat is effectively carried away by convection though.

IF you guys are going to dick around with any sort of DIY pressure vessel with these materials, make sure that you wrap it with duck tape a few layers thick. This will keep the fragmentation from a burst from slicing you up to ribbons
