A lot of pretty interesting celebrity belongings have been up for auction lately, but perhaps the strangest yet is a jar filled with Australian singer/songwriter Sia Furler's breath.

Billboard is reporting that the 38-year-old "Chandelier" singer is donating the jar of her breath that will be auctioned off at the Adelaide Film Festival's film quiz night charity event on October 31.

The news of the interesting item up for auction was announced on the Adelaide Film Festival's website. The director and CEO of the festival, Amanda Duthie, got in contact with Sia, and asked her to contribute to the charity event.

About Sia's unique contribution to the charity event, Duthie said, "Gorgeously and magnificently, she breathed into a jar for us. Her breath is in a Mason jar with silver sealing wax, so no one can accidentally open it. Whoever wins it will be able to break the seal – or just let it be."

A few other items up for auction include a role as an extra in Adelaide-born Anthony LaPaglia’s film, A Month of Sundays, that will begin filming early next year, as well as the chance to be a street clown in Adelaide’s famous Credit Union Christmas Pageant.

Sia released her latest album, 1000 Forms of Fear, in July, which features her hit song, "Chandelier." The video for the song has since been parodied by many people, including comedians Jim Carrey on SNL and Jimmy Kimmel on Jimmy Kimmel Live.

Proceeds from the charity event will benefit Adelaide-based filmmakers.
