In Australia, 7-Eleven has Bring Your Own Slurpee Cup Day, which allows people to bring in cups and containers of any kind to fill up with slushies for the same price as a normal-sized cup. This results in many creative containers ranging from buckets to teapots to shoes.
This year, Leo Burnett Melbourne made 3D-printed Slurpee cups based on the sound waves from the product's own radio spots. The circumference of the cups was made by the voice over sound waves, while the height and shapes were made from the sound effects.
Touting themselves as the first ever cups made of sounds, the Slurpee Sound Cups act as a great marketing strategy for the drink itself, the 7-Eleven stores as well as the Bring Your Own Cup Day promotion.
