Getcha some facial tissues. A whole box if you've got it handy, or a dish towel, or some toilet paper. On the count of three, you're going to snort a line (or pile) right up your nozzle. You're immediate thought is going to be "It's not that bad..."
And then it's going to burn like heck. But it's not an unbearable burn, it's a crazy funny hilarious I can't believe I just did this to myself burn.
I snorted straight cayenne powder up my nose with my 16 year old. It was a hoot! We laughed so hard! Our eyes were watering, our noses were running like a faucet, and we sneezed for about 10 straight minutes, almost laughing ourselves to death.
You gotta leave it in there and not blow it out for about 5 or 10 minutes. Wipe your nose, wipe your eyes, sneeze like crazy, but don't blow it out.
When you finally do blow your nose, you'll be amazed. Calm down, then do the other side. :)
