Sometimes I like to experiment with different foods to see how the smell of my farts turn out. The results are quite interesting I usually make a hypothesis and try to predict how the smell will turn out. I like to catch them in a bag or a jar and smell them it really is satisfying. Do you have trouble breathing or pooping then try farting.
