I can do it, but I always end up using three or four tissues. And the first shot invariably requires a thorough hand-washing and check in the mirror for mustache debris. I find it easier to just hold one nostril shut and blow into a sink, but that’s not always convenient or possible.
What if you were to just hold one nostril shut and blow it into the tissue? That’s basically what I do, with it folded in half. Fold in quarters, wipe again. Fold one more time for a final cleanup. Each fold is like a fresh tissue, but I still wipe three times.
There’s often the hardened piece of snot that you feel going POP! out of your nose like a champagne cork, but then you can’t find it - it’s not on the tissue, it’s not on your hands, or clothes, or face - it’s nowhere to be seen - except straight away by the next living human you encounter, who notices it stuck on your adam’s apple…
I like blowing my nose in the shower - my family all disapprove of this, but it’t the best time to do it (the steam helps loosen everything up), and it saves on tissues.
Please don’t try to save on tissues.
Oh god. ::blech:: Please if you blow snot rockets in the shower, clean them off the walls. My ex-husband had a problem in this area and it does not make for a pleasurable showering experience for the next person to have to see your nose babies everywhere.
To be perfectly honest, I too do the sink/shower/on the ground type of nose blowing. Everytime I have ever tried to use a tissue, snot invariably gets either on my face, on my hands, or somewhere else that I don’t want it. If I’m in the house, and I have to blow my nose, I just go to the bathroom, and do it into the sink or trash. Then one tissue is enough to wipe off the edge of my nostrils, and I’m good to go.
Same thing if I am outside. If I am cutting grass or something, and some allergy-related snot needs to be let out, it goes on the ground. Obviously I don’t want to be rude or gross when I am with people, so its not like I just hold one nostril and let fly while in Red Lobster or whatever, but when I am alone, I think its perfectly fine.
And yes, I do it in the shower if I need to. But the water always washes it away, its not like I get it all over the wall and the curtain.
TMI time: I also pee in the shower! :eek:
I use my pee to clean my snot rockets off the walls. 
As long as you clean them off… 
I envy you who can blow.
One time when I blew my nose, I got this vacuum seal thing going on in my sinuses. It sucked my soft palate into the inner recesses of my head so that I could barely touch it with the tip of my tongue. After a few moments, the suction was released and my soft palate returned to its normal place. Still, it creeped me out. Now, I only squeeze what snot I can into a Kleenex or hork it down the back way.
