The Rules: Take a tablespoon of powdered cinnamon and swallow it without any water.
The Gist: This is hard to do, as cinnamon is dried-out malice. Even the Mythbusters agree.
Observations: I learned that I have a lot of cinnamon in my cupboard first and foremost. I think people buy it for me assuming I am incapable of living like a real human and cinnamon would help me achieve normality. I can't recall ever using it.
I've watched videos of the cinnamon challenge enough to know what was going to happen to me. Did you know what was going to happen to me? There's coughing and gagging, sometimes even vomiting. None of these really appealed to me, but there are literally hundreds if not thousands of videos online of people doing it. What's the payoff?
Pain. Pain is the payoff.
There is no payoff to doing the cinnamon challenge. The moment you attempt to swallow a spoonful of cinnamon, you can literally feel a searing tightness work its way down your throat, as though your body is saying "What are you, fucking stupid?" and trying to clench itself off before you do more damage. The worst part is that, if you're extra special stupid like me, the moment the cinnamon leaves your tongue and fills your mouth with a billion desiccated granules of desert-like awful, you panic and suck in quickly, trying to free yourself, which means you both swallow and inhale the cinnamon for a one-two punch of dumbassery that makes the spice invade two sections of your body where it doesn't belong.
