Properly produced, a pointless bar trick is as much a how-to as a Mario Batali cooking instructional. We are non-discriminatory in that regard. While curating, we focus primarily on the INTENT of the video.
In truth, WonderHowTo has indexed multiple versions of this same whiskey/water trick. I happen to enjoy the childish techno music.
Osmosis. Liquid density. Don't overthink this one. Just enjoy.
