Here are some nutty fellows, the Slow Mo Guys, the Cinnamon Challenge (Don't do it, may not be safe and burns), you try to swallow a spoonful of cinnamon, apparently this has been a bit of an internet sensation but I never heard about it. Anyway, it seems you puff out the powder like a dragon breathing out smoke.
No thanks, some sites warn you not to even try it but it is kind of funny to watch.

Even at risk for pneumonia. Thought I'd add in the warning.
