Place shot glasses in the freezer for at least 15 minutes before preparing the Duck Fart to keep layers distinct and prevent premature mixing while maintaining the perfect serving temperature.

Pour Kahlua first, then slowly layer Bailey's over the back of a bar spoon, and finally float Jack Daniels the same way—the density differences (heaviest to lightest) create perfect separation when done correctly.

Keep your Jack Daniels and Kahlua at room temperature while Bailey's can be slightly chilled; this prevents thermal shock that causes layers to mix and ensures smooth pouring for clean separation.

Hold a bar spoon horizontally just above the previous layer and pour slowly over its back—this disperses the liquid gently across a wider surface area, preventing layers from breaking through and ruining your shot.

Present the shot to guests immediately after layering while the three distinct colors are still perfectly visible, as the layers will gradually blend within 2-3 minutes if left sitting.
