AS Ken Hinkley slammed a plate of shaving cream into his captain's face, Port Adelaide kicked off the Ultimate Pie Challenge for the Childhood Cancer Association.

The CCA is Port Adelaide's official charity partner and aims to raise money to support its important work providing care and support to the patients and families affected by Childhood Cancer.

The challenge is simple - write your donation to the CCA on the back of a paper plate, fill it with whipped or shaving cream and whack it into your face.

Finish off by nominating three people to do the challenge as well.

It's hoped that the Childhood Cancer Association will raise a significant donations tally - targeting $1 million by the end of April - to support their vital services. 

Based opposite the Women's and Children's Hospital in North Adelaide, the Childhood Cancer Association receives no government funding and so relies on public and corporate donations to operate. 

Nearly 400 families currently receive support from the Childhood Cancer Association and Travis Boak has been a long-term ambassador for the organisation since moving to Adelaide with the Power.

The Childhood Cancer Association is the official charity partner of the Port Adelaide Football Club.
