How can I demonstrate Flatulence?

[audidot]

I've been trying to think of a unique science project, and I think it would be fun to do it on the causes and different types of flatulence. However, I need to have some type of display and possibly something "hands on". Does anyone know of a way I could demonstrate flatulence or artificially create the smell with household chemicals?

Audidot,

I would definitely clear this topic with your teacher before you do a lot of work on it. That said, here's a website with a lot of info:

http://en.wikipedia.org/wiki/Flatulence

The odors are usually caused by the bacteria normally found in your digestive tract and include gases like hydrogen sulfide (in very small concentrations). Hydrogen sulfide is a very toxic gas and you should not try to make it!!

Good luck!
