Ok, exams are coming up, and i have some trouble in chemistry. Im pretty good at it, but i want to do something original, but everytime i find a cool recipe, it contains something i cant use in school like potassium, Sodium etc. etc.

- I want to do somthing colorfull, but like, it all contains all this baaad stuff.

Any ideas?

Just like "the HCl Fountain" Just no darn sodium. (sodium chloride is ok though)

- but just Colorfull

give a list on what is banned it will make it easier for someone to help you

ehm, everything with Sodium, potassium, and like radioactic things. We dont have any gasses or air things, but i can make em my self. (:
- But mostly potassium and sodium things. I can use NaOH though (:

are you looking for explosions, or burning, or fire, or something else, and as for sodium can you use NaCl? Also, does it have to be done in class or outside of class?

Are you actually planning to use home made pyrotechnics in school?????

dont even get me started on how much of a bad idea that is

That is ok in dk. Our teatcher is mad.

- He startet our first lesson by, "dont ever do this"
- He then did. Make black powder, and ignite it.
- Blow up some different stuff.
- All sorts of "dont do" stuff. In denmark, people are not like, "omg, an airsoft weapon in school" Or "Heey! its illegal to play with fire" they r cool.

I once fired a 75 g Flash grenade at a school thing. None was there to be said. Oh yes, my english teatcher asked med for a recipe. (:

your school sounds very messed up, still i wouldn't try homemade pyro in school
untill you at least have experince with doing the basics

anything homemade is going to be unreliable to some extent

Best to start with basics like black powder and flash powder

Of course i can use salt, it has to be done inside, and i can't JUST be cool, i need an actual reason why i did what im gonna do ;D No exsplotions, Burning fire stuff is cool to, and it is INSIDE my class, no not to much Chlorine gasses. ;D
