Does altitude change the sound of speakers??

To find your answers to these and other pressing questions, read Mary Roach, author of Packing for Mars, and other scientifically tangential books. 

Actually, it was from the first Alien movie advertised as “in space, no one can hear you scream”. I still have the movie poster.

Yes but my kid brother had the "In space no one can hear you fart" T-shirt. 

 Boy, this thread sure went in the proverbial toilet quick!! 

Mary Roach seems like some rennaisance woman. Topics of her books are from cadavers to gastroenterology (that tract for some reason declared a taboo in the intro) to needs in space.

And yet, there is some sucker working whole life on one small molecule for a salary. and she never gets mentioned anywhere. Not fair.

Are there roaches in space?

Can someone please put out the Mary Roach Motels tonight?
