Scientists have recently discovered nanodiamonds in the flames of ordinary candles. They are produced at a rate of about 1.5 million per second. Unfortunately they are also burned up at this rate and released into the atmosphere as carbon dioxide. Still this finding may prove useful in the ongoing search for economical ways to produce diamonds.

In the mid 1800 s scientists successfully passed an electric current through a vacuum in a glass tube. They saw a glow from the tube that seemed to emanate from the negatively charged plate...

The Earth is clearly old, but exactly how old was difficult to work out. People long believed the Earth had only existed for several thousand years. Then, in the 1800 s, a study of geological...

2011 is the international year of Chemistry. But what do Australians know about it?

On mobile, click here for the answer: http://www.youtube.com/watch?v=qQCVnjGUv24 When ice is put under pressure, its melting point decreases. When that pressure is removed it goes back to being solid. This process is known as regelation . In this experiment regelation of ice is attempted with copper wire and fishing line of the same diameter. Which will pass through the ice first?

What passes through a block of ice more quickly, copper wire or fishing line?

When pressure is applied to ice, its melting point is reduced so it turns to water. When the pressure is removed, however, it turns back into ice. This process is called regelation. Big thanks to Art of Ice Sculptures www.icesculpture.com.au who donated the beautiful block of ice.
