About ants and water filters - video on nanotechnologies
Entertaining and informative: The young South African scientist Dr. Anita Etale explains the benefits of nanotechnologies.
How small are nanoparticles? What are they useful for and in which technologies are they used? In order to answer such questions in a vivid way that can be understood by laypersons, Dr. Anita Etale from the Witwatersrand University in South Africa has created an animated film.
Her main target group are children and adults in mining settlements around Johannesburg, whose supply of clean, healthy water could often only be guaranteed through the use of nanofilters. Many of the inhabitants are sceptical about this type of water purification for cost reasons, but many are also unaware of how harmful unfiltered water from the vicinity of mines can be. The film text is written in Zulu, one of South Africa's eleven official languages, which is understood by over 50 percent of the population. There are also subtitles in English.
Anita Etale financed the film, which was produced for public relations work, with additional funds for science communication from the Foundation. The entertaining clip, which is well worth seeing, is shown in schools and at information events.
