Bordertown High School and Keith Area School have unfortunately come up short in UniSA Mount Gambier's bottle cap collection challenge.
The university created the challenge in partnership with Envision, which takes plastic bottle caps and recycles them into 3D filament, prosthetic hands, and other usable STEM items for those in need.
The challenge ran during Weeks 1-5 of Term 3 and offered two prizes of $500 for the primary and the secondary school that collected the most bottle caps.
A total of 16 schools across the South East took part in the challenge, with each school looking to take out the cash prize.
UniSA Mount Gambier's Michele Cranage said due to the size discrepancy between a number of the schools, the challenge introduced a system to make the competition fair to smaller schools.
"Each school's total bottle cap weight was divided by the number of students involved from each school," she said.
Regardless of school size, all students worked incredibly hard to collect as many caps as possible, with the university revealing a collective total of 239kg's was collected during the five week period.
Announced on Wednesday, the winner of the primary school prize was Glencoe Central Primary School with 30kg and the secondary school prize was Kangaroo Inn Area School with 34kg.
Ms Cranage said the 239kg of bottle caps are currently waiting to be collected and sent to Envision's warehouse in Melbourne.
Unbelievably, it only takes approximately 500 bottle caps to create one prosthetic limb, and ultimately change the life of a child forever.
Although Bordertown High School and Keith Area School missed out on the cash prize, both schools were happy to be a part of a great cause which has the potential to change the lives of children across the country.
With the challenge officially completed, Bordertown High School still has an motivation to continue collecting the plastic bottle caps on behalf of the Rotary Club of Bordertown.
The school encourages locals to also continue collecting plastic caps and dropping them off at the school's front office.
