The Finnish animation studio Undo teamed up with a Finnish production house Komia to create this spot for Finlandia. The film is directed by Juuso Syrjä.
Fluid simulation was used to create the impossible shots where the vodka would rise up and form the shape of the bottle. A fairly complex setup was made in Realflow to direct the fluid growing, and a lot of growing collision geometries were used to move the digital fluid to match the shape of the bottle.
Mission accomplished!
