The phone is the shaker. This is the view from inside it: a Rum Sour poured in layers, iced, capped, shaken hard and left to settle, with the sound of a real bartender’s shake synced to every slam.
The beats
What’s in the tin
60ml
Gold rum
30ml
Lemon juice
20ml
Simple syrup
A Rum Sour. The layers stack by real density: syrup ≈ 1.30, lemon ≈ 1.03, rum ≈ 0.95 g/ml. The liquid is a 2D FLIP fluid simulation, the ice is rigid bodies, and the look is comic ink, halftone and flat colour bands.
