The player must use the 1.5L and 4L containers to fill 3 terminals requiring 0.5L, 1L and 3.5L of Eagleade. That can be done by transferring and emptying the liquids between the two containers given in a precise order detailed in the 2016 Easter event page. Note that the terminals require exact amounts of the drink; ie. the terminal for 1L can't be filled by using Small container (0.5 litres) twice on it. It can be emptied by right clicking on it and selecting "Empty" or using it again on the dispenser. The container is not removed from the inventory if players leave the area.
