Friction! It’s what makes the world go rou— No, wait. That’s not it.

Friction. It’s what keeps the world from spinning off into spaa—- That’s not it either.

Friction… It’s what keeps your shoes from being too slippy, but also, like, just slippy enough?

*Sigh* Also, dog bark science. Enjoy!

QUESTIONS

Julian: "What would a perfectly frictionless surface feel like?" from Adam

Trace: "How bad would a dog's bark have to be to be worse than it's bite?" from Grace

(In a previous version of the show notes I hadn't updated Grace's question. Sorry Grace! Listener Tracey emailed and caught it. Thanks…
