Acidko is the most popular acidified milk product in Slovakia. However, it was notoriously known for its packaging with a complicated air-sealed opening cap that had to be torn away and was a common cause of milk stains on shirts.
The new cap was presented in an interactive video where people could choose whether they want to open Acidko in the old or the new way. The campaign was supported by a 360° post, where in order to open the drink all the people had to was to rotate their phone by 360° degrees — just like the new cap. Altogether, this small social media campaign reached 900 000 users.
