Have never seen that and don't if it's real or not. But from other stuff I've played with I would think that something like this is possible.
Nitrogen Tri-Iodide It's unstable but the ingredients can be obtained easily and it's not hard to produce. We played with some larger amounts as one of my friends had a farm and his father was also our chemistry teacher. We also experimented (read played with) Sodium and water.
It's amazing when we get together and remember the stupidity we lived through and also that we were lucky enough to not get hurt, maimed, or killed.
