In this video a man sticks his hand into a jar full of molten sodium acetate and has it crystallize with his hand inside.
This works because the substance is not “ice” as in water, but a different substance called sodium acetate trihydrate. Normally solid sodium acetate was melted into a liquid that was then supercooled to below its melting point. In this state, adding nucleation sites, like the crystals on the man’s hand, rapidly causes the rest of the sodium acetate to crystallize.
A group of young British Muslims have joined the fight back against Islamic State militants with a video and social media campaign.
After the murder of David Haines and kidnapping of Alan Hemming, the East London-based group Active Change Foundation decided to voice their anger.
They set up the #notinmyname campaign to spread the word that British Muslims reject IS, its ideology and actions and to show that IS do not represent the Islamic faith or the Muslim community.
Hanif Qadir, founder of ACF. said: “The murder of an innocent man has no justification in any religion or walk of life.
“These terrorists ISIS are not true Muslims, they do not practice the true teachings of Islam; peace, mercy and compassion, and they are the enemy of all mankind.”
