One of twenty
In August 2015 Google named twenty global finalists for its annual science fair. Lalita Prasida Sripada Srisai of India appears among them, listed fourteenth, with a project described in five words: absorbing water pollutants with corn cobs.
That listing is the whole of the published description. The article reporting the finalists gives project titles and names, and no biographical detail, no technical method and no results for any individual entrant, including hers.
What the project proposed
The proposition in the title is a clean one. Corn cobs are a by-product with no market value in most places that grow maize, and water contamination is a problem concentrated in exactly those rural economies. A filtration medium that can be picked up from the ground after harvest is, in principle, a solution matched to where the problem is.
What the source does not provide is the substance of the science: which pollutants were targeted, how the cobs were prepared, how absorption was measured, what removal rates were achieved, or whether the results were independently checked. Those details were presented to judges but are not in the published record used here.
The 2015 fair
The Google Science Fair narrowed its entries to twenty global finalists in early August 2015 and spotlighted them through the month, before a final judging event on 21 September 2015 at Google's headquarters in Mountain View, California. The prizes on offer included a $50,000 scholarship.
Andrea Cohen, the programme's leader, summarised the cohort in a line quoted at the time: “The 20 discoveries of the global finalists began as simple curiosities, and have the potential to change the world.” The article does not state how many entries the twenty were selected from, or how many countries submitted them.
The award question
The research note behind this page records that Lalita Prasida went on to win the Community Impact Award at the 2015 fair, citing a Wikipedia list of winners. The source used for this article confirms only her selection as a global finalist, and the award is therefore treated here as unverified rather than stated as fact.
The distinction matters. A place among twenty finalists drawn from a worldwide field is itself documented and substantial. An award on top of it would be a further, separate claim, and it needs a source that states it directly — ideally the organisers' own winners page or Indian press coverage from September 2015.
What is documented — and what is not
The firm facts are her selection as one of twenty global finalists at the 2015 Google Science Fair, the subject of her project, her country, and the shape of the competition around her: the August announcement, the September judging at Mountain View, and the $50,000 scholarship among the prizes.
The gaps are wide. No age, date of birth, home town, state or school appears in the source used here, no photograph, no quotation from her, and no follow-up reporting of any kind. Nothing establishes what happened to the corn-cob method after the fair, whether it was tested at scale, or what she has done since 2015.
