I've already got it all planned out, and truth be told, I feel like I shouldn't tell you guys this. Catching the farts is the easy part.

Sit in a bathtub, with an upside down canning jar, and catch the fart bubbles in the jar under water. The gas will displace the liquid in the jar. After collecting a few farts, you can cap the jar while it's still under water, and there will be no way for the fart smell to escape.

Now the question is, if I commit and fill a whole jar with farts, then send it to my brother through the mail for mxas. Will it stink when he opens the jar?

It gets better. What if you could make the fart gas into fart liquid by keeping it under enough pressure to condense it..fart spray?
