Whoa hey Rob and Jairen get way off-topic to start this one out. Hold still long enough and you are bound to learn about glass. Or listen long enough to hear Rob describe something as "dingy" ooooh yeah. Win-win either way. Super fun episode here for sure. Come and see through the looking glass, stare into the windows of time, and enjoy this episode on glass! Not satisfied? Send an email to [email protected]
