Everyone in my family just turns their head to the side and lets their sneeze rip into the house. I've only convinced one of them to cover their sneeze sometimes.
I told my sister that if she couldn't grab a tissue in time, then she could pull the collar of her T-shirt up over her nose (a move I copied from my friend from Vietnam) and she said "that's gross!" 
...But coating the entire room in a fine mist of the same stuff isn't!? That's like opting to throw your turd at a moving house fan instead of shitting your pants.
I also had a classmate who would sneeze with so much substance that I could literally see chunks of snot hit the floor. 
It's an american tradition to spread diseases.
