Reactions is a show that uncovers the chemistry all around us. We answer the burning questions you’ve always wanted to ask:

-How can I get my smartphone battery to last longer?
-What if humans could photosynthesize?
-How can I get my teeth to look whiter?
-Why is pizza so delicious?
-Is it OK to pee in the pool? (Spoiler: No. No it’s not. Stop it.)

Reactions are happening everywhere. But the best ones are right here on YouTube. Subscribe!

How Do We Know the Age of the Earth?

Subscribe! http://bit.ly/ACSReactions Head to www.acs.org/ncw30years to find out more about National Chemistry Week! The Earth is 4.565 billion years old, give or take a few million years. How do scientists know that? Since there’s no “established in” plaque stuck in a cliff somewhere, geologists deduced the age of the Earth thanks to a handful of radioactive elements. With radiometric dating, scientists can put an age on really old rocks — and even good old Mother Earth. For the 30th anniversary of National Chemistry Week, this edition of Reactions describes how scientists date rocks.
