Whoa, that’s a wild theory! I mean, if crema were quantum tunneling, we’d be brewing Schrödinger’s espresso, right? I can picture the little beans in a potential well, hopping out like they’re auditioning for a quantum dance. But honestly, I’d love to test it out—grab a fresh dose, crank the pressure up, and see if the crema pops like a quantum leap. If it does, we’ll have the first coffee‑based lab on tunneling! If not, I’ll just argue that the crema is pure, stubborn art. Either way, it’s a perfect experiment for a coffee lab, so let’s fire up the espresso machine and see what happens.
