Nitrogen Triiodide is a contact explosive, which means that even with the slightest touch, it'll release a large amount of energy all at one time and explode.
Most of the explanation of this property can be attributed to the fact that the molecules are highly unstable.
In this video, you'll see Nitrogen Triiodide react to various touches from different objects, and in slow motion with high-speed cameras. Although this is cool, we recommend you don't try this at home.
