What's the chemistry of sticky stuff?

#011 Rebroadcast

Why is honey sticky but salt isn’t? What’s the difference between things that stick and things that just feel sticky? In this episode, Melissa and Jam dive into the chemistry behind adhesion, cohesion, and the forces that make substances cling to surfaces (and to our fingers). They explore intermolecular forces, viscosity, and why some things are nearly impossible to separate once they’re bonded. Plus, Jam shares a hilarious mix-up of words, and Melissa breaks down why this topic turned out to be trickier than expected!

Topics Covered:

• The difference between adhesion and cohesion

• Intermolecular forces: the unseen power behind stickiness

• Why some things feel sticky while others are just stuck

• How temperature and viscosity affect our experience of stickiness

• Why hydrogen bonding plays a key role in making substances cling

• Listener-submitted answers on the “scientific word for sticky”
