The event, now in its second year, is a drive by an organization of parents with children diagnosed with cancer.

People could fund a rubber duck who would then race down the canals with the first duck bringing a prize for the owner.

The drive netted more than 110,000 euros in total. The money will be used to fund a support center for young cancer patients and their parents and to purchase cancer patient monitoring systems for the Tartu University Hospital.

The event, inspired by a similar drive in Luxembourg, aims to raise awareness about children who have cancer and the difficult situation their families face, calling for donations by businesses and individuals to fund treatment and support services.
