It makes people sneeze because pepper contains a chemical called piperine, it's what makes the pepper spicy. When you breathe bits of pepper into your nose, that chemical really irritates your nose's lining, which makes your body sneeze to get rid of it.
You can use pepper to make yourself sneeze. If you smell the pepper you will probably sneeze. The nose is very sensitive to pepper.
Salt doesn't make you sneeze because, well basicly its salt. but pepper does make you sneeze. hope this helps:)
The same things that make a human sneeze....ie black pepper.

The main reason pepper makes us sneeze is that it has a coating on it of a chemical called piperine. This is the chemical that makes pepper spicy. When pepper gets inside your nose, this chemical really irritates its lining, triggering your sneeze reflex to expel it. A secondary reason it might make you sneeze is that pepper is usually ground up into tiny bits, which can get in your nose and make you sneeze for the same reason as things like dust.
You can't voluntarily make yourself sneeze, it's an involuntary reflex. You could induce a sneeze, though, by sniffing dust or pepper or tickling your nose with something.
