Continuing today's theme of slo-mo drinks: here is a double-helix-esque vortex in a beer. Beverage and commentary by Greg Foot.

AUDIO WARNING: This clip is quite loud. One reviewer commented "So that's what the screams of 1000 damned souls sounds like." (Charles Weber, 2016). Sorry about that. I recorded and uploaded it in a pub.
