That Little Ping-Pong Ball in a Guinness Can Is an Engineering Marvel

I bartended for nearly a decade, and I treated every Guinness pour as if it were a delicate flower.

Regardless of whether it was a slammed Saturday night or a quiet Monday lunch, Guinness drinkers deserved a creamy, deep, dark, and thick pint.

The two-part ritual took me about 115 seconds to pour (115 seconds? That was nickname in college).

I took pride in serving every single pint o’ Guinness with passion and precision.

My Guinness pouring mindset was sort of like what Yankees Hall of Fame Joe DiMaggio said about playing hard: “There is always some kid who may be seeing me for the first or last time, I owe him my best.”

And look, we live in a world where putting a camera inside a grain of sand or some shit is now commonplace.
