Lead - Periodic Table of Videos
Lead is a soft, heavy, poisonous metal. It is often used for radiation shielding. In World War Two it was used as a submarine camouflage because with simple in the field chemical reactions it can be changed from black lead sulfide to white lead oxide or sulfate and back. Tetraethyllead was used as an antiknock additive in gasoline until the toxic and environmental impact became public.
Dec 31, 2008

The solution changes color as the vanadium is reduced from oxidation state V to IV to III and finally II.
Jul 18, 2015
NaK
NaK is an alloy of sodium and potassium that is liquid at room temperature. It was of interest as a coolant for nuclear reactors but there was concern it would dissolve metal pipes so it was tested by circulating it in pipes in a laboratory environment. A group at the Unversity of Nottingham built a similar rig from glass and applied on electric current to display a liquid metal fountain.

Um Ghayeb: Mother of the Unborn

The absolute truth lies in the notions of life and death...fertility indeed is the miracle of creation. But does it answer the question of happiness, or is it just an illusion? In a forgotten corner of Egypt lives a woman who is yearning for a child. Having no option but to live on the fringe of her community because of her infertility, Hanan lingers between a dream that is slowly slipping away and her struggle to find a place where she belongs. While everything that surrounds her bustles with fertility and mortality, she wonders how to give meaning to the time that she has in between.

Revival

REVIVAL is a dance feature film based on the rare folk dances in India. It is the narrative of a street dancer trying to explore Indian folk dances by travelling to the remote and dangerous naxalite infected areas. The film is all about the transformation of a dancer by digging into folk dances of India thereby understanding the nuances and the true essence of dance itself. The film reflects the raw and rustic lives of the real folk dancers thereby bringing the true perspective on screen through the eyes of the street dancer. Shot over a span of two years in Andhra, Telangana and Odisha, this film is an out and out dance film and whether the street dancer manages to unearth these rare folk dances, learn them and eventually perform with them in such testing conditions without food and shelter forms the crux of the film.
