How To: Make DIY Nitrogen Triiodide from ammonia & water purification iodine crystals

where can i get all of those ingredents?

Found some at wal-mart but they can be found in most stores that have cleaning supplies and other related things.

I always use concentrated ammonia - not sure how easy it is to get hold of.

I made some back when was bored at university. This stuff is wickedly unstable. It blew up while i was washing it down in the filter paper. It left little specks all over the lab floor so for weeks afterwards people were setting it off when they walked into the lab. If you're going to make take the right safety precautions.

Nitric acid from a car battery? Every one I know of uses sulfuric acid. However, since English is apparently not your first language, perhaps they use it in your country. But I doubt it.
