The subreddit AskScience is an intellectual gold mine. Curious folk of all ages pose rousing scientific questions to be answered by scientists and experts.

Last month, user sleepwalken asked a question that was both hilarious and thought provoking:

“If you farted hard enough in space, could you move yourself around?”

The slightly sophomoric, yet stimulating question quickly rose to the top of the forum, and received a serious response from user VeryLittle, a physicist and moderator of the Physics subreddit.

“Essentially, farts are rocket fuel,” he (or she) replied. “Gas diffusing will carry a small amount of momentum backwards, so it must exert a force on the person, pushing them forward.”
.
However, that force would be very small, he calculated. The average person produces roughly one liter of flatulence a day, composed mostly of hydrogen, carbon dioxide, and methane, along with smaller amounts of nitrogen and oxygen. “That comes out to 0.5 g of flatulence every day for a normal person,”
