_______________________ I Nitrogen Tri-Iodide I ----------------------- Materials: Iodine Crystals- 4 grams Ammonia- enough to cover crystals, twice Distilled water- enough to cover crystals once Put iodine crystals in a pan, then pour the amonia over them. Let sit for 15 min., then pour off the liquid on the top into a test tube(or what ever). Do this same step a second time, and pour the liquid into the same container. Then pour distilled water over the iodine crystals. Let that sit for 15 min. , and pour off that liquid into the same container as above. Mix the liquids together(preferably with a glass rod), and that is the Nitrogen tri-iodide. Save the iodine crystals for a later use of the same thing. You can use the crystals until they disolve. The NI3 is good stuff to use for fun. It makes alot of noise, but has little force. This stuff has been used at Parent-Teacher meetings, or any such gatherings at schools, or buisiness. The NI3 is exreamly stable in its liquid form. But when it is allowed to dry, it becomes so unstable that ONE DUST HEAD could set it off. And when used in ball form, it can be dangerous, since it will be more compact and have more force.
