An Australian company created a gold toilet paper roll valued at nearly $1 billion made with 22 karat gold layered paper that releases gold nuggets while used and comes with a bottle of champagne. Gold ink is growing in popularity for printing due to its ability to produce high quality, long-lasting printed images and coating CDs and DVDs in gold can make them more durable and resistant to scratches. Gold is also starting to be used more in 3D printing applications.
