I think one reason iodine is restricted is that too may kids know what happens if you mix it with amonnia. At least a friend of mine in high school (late 1970's) complained he had trouble buying it to make explosives!

>It is always very funny to hear such things. I wonder why iodine would be considered as being a dangerous chemical. Don't mix it with ammonia though, it would make a black precipitate, nitrogen iodide. That black precipitate is an explosive compound sensitive to warmth, wind, friction, shock, electricity, everything. It's very sensitive when dry. Chemistry students used to prepare it as an experiment.
