This week Reactions is taking a look at some space science and chemistry. We’re looking where the elements came from.

As Carl Sagan famously said, “We are made of star stuff.” Whoa. It’s a mind-boggling thought, but what exactly did he mean? Check out the video to find out… Subscribe! http://bit.ly/ACSReactions

Nov. 9th is Sagan’s birthday. To celebrate, Reactions teamed up with the American Association of Chemistry Teachers (AACT) and best-selling author Sam Kean to explain the chemistry behind this iconic quote. Watch the video to find out how many of the elements that make up you (and everything else) were forged in the nuclear cores of stars billions of years ago.
