As the drinker’s hand gets sweatier, the scantily clad mascot’s bikini disappears, leaving little to the imagination.

The concept came out of a bar-room discussion between the beer’s brewers: Hamish Rosser, drummer with ARIA-winning rock band The Vines, and his mates, actor Richie Harkham and artist Jarrod Taylor.

“We had the idea of a pin-up girl from the get-go, we thought everyone uses women in their advertising campaigns so why not put it on a bottle,” said Rosser.

Rosser, who actually has a degree in chemical engineering, added: “So we had this idea of the disappearing bikini and did some research into disappearing ink. Then we did a few trial runs and when we realised it worked we were stoked, we were over the moon.”
