Stickiness: we know it when we see it-- or when we feel it under our feet at the movie theater. But what is stickiness, scientifically speaking? How do geckos climb? Why don't post-it notes ruin our books? On today's show we'll ask scientist Laurie Winkless about her new book, "Sticky," and figure out what holds it all together.

GUESTS:

• Laurie Winkless - A science writer, physicist, and author of the new book, “Sticky: the Secret Science of Stickiness”
• Dr. Alyssa Stark - A professor at Villanova University. She runs a lab that studies biological adhesion.
• Will Coldwell - A freelance writer and regular contributor to the Guardian, Economist and Financial Times. He is the writer of the Economist article “Bursting the Bubble: How Gum Lost Its Cool.”
