I'm not getting this one at all
Got the trick, no problem. Nice big ass nail. Tap it in with the top of a coffee mug (always handy and reverbarates nicely.)
But the reactions I get with it are rubbish! No one seems fussed or even grossed out. I had a much better response with the arm on the sidewalk twisty thing.
Best response when i put the nail in first, tucked it under the nostril and produced it without showing people where from!
Missing something here.

PS. From my medical side I should say nobody should do this ever

. But if you must, sterile is nowhere near as important as strong. The nose is there to collect the c*** (not the best) in the air you breath so if you don't break the skin its safe. If you DO you've just shoved it over all the c*** (not the best) collected on the nasal cavity so you're stuffed anyway. But using a cotton bud as sombody suggested is dangerous because fibres, or god forbid the whole tip, could get left behind and cause irritation. Also be aware of irritation, it wants a smooth tip. Something smooth and hard with a rounded tip is best. I started with a 4 inch nail after i polished the tip to rounded head. Longer also means less chance of getting the whole thing stuck!
Like i say, nobody should do this!
