“We all buy fruits and vegetables and they’re never ripe. So, I wanted to come up with a way for the avocado or any other fruit and vegetable to work around you” she said.
Bay of Plenty Science Fair 2019 winner Anamaya Taylor. [NIWA] The thirteen-year-old tested several “old wives’ tales and different methods”, and found out ethylene, an organic gas, was the most efficient way to speed up the ripening process. After carrying out the experiment, Anamaya designed a prototype to ripen the fruit as quickly as possible.
She modified a soda stream, an appliance normally used for carbonating water, to spray gas into a bag holding an avocado.
Tracey Burton, a freshwater ecologist at NIWA, said Anamaya’s project paired thorough scientific investigation with ingenious product design.
“Anamaya’s project is an excellent example of scientific rigour and innovation. The Avocado Time Machine was a worthy winner among many clever and original projects”.Judging and prizegiving was held at the Harvest Centre in Rotorua. Thirty-six judges were tasked with judging more than 80 entries against a range of criteria including identifying and researching the need, scientific thought and understanding, and presentation. Interviews with the students also helped the judges determine the winners.
Providing major sponsorship for many of the science fairs throughout New Zealand is part of NIWA’s long-term commitment to enhancing science and technology for young New Zealanders. NIWA is also a major sponsor of the Auckland City, South & East Auckland, Waikato, Canterbury-Westland and Wellington Science and Technology Fairs.
