I recently bought some sneezing powder just to see how it works. I often suffer from allergies and sinus issues due to a deviated septum, and so I thought it might be fun to see how well this stuff clears my nose out. I start by taking a pinky nail size sniff of this sneezing powder and wait for it to work. Boy, does it work fast! I sneeze loud and hard multiple times, making my nose run so much I have to blow it! I do this a second time with the same results: Powerful sneezes, runny nose, watery eyes. It's safe to say this sneezing powder works!
