Ever Wondered About... Eggs?

...solids melt as they get hotter, but eggs do not. They start as quite liquid in the fresh state and when they are heated, they go solid. This odd behaviour is a result of the effect of the heat on the proteins they contain. The strands of protein in both the egg yolk and white are folded into precise shapes, each molecule forming a minute ball called a globular protein....

DIY: Taking the Caffeine Out of Tea

...liquid, which if heated further will (normally) vaporise to a gas. However, solid caffeine, when heated forms a vapour directly, without passing through a liquid phase. This process is called sublimation. Caffeine sublimes at around 160° C and, when the caffeine vapour cools, it re-forms the pure solid. It’s therefore a very convenient way of separating it from...

...liquid is, however, still supersaturated and will continue to release the carbon dioxide until it goes "flat". Carbon dioxide Carbon dioxide is a very stable compound, which doesn’t burn or support combustion. If it’s cooled to -79.9 degrees Celsius it immediately forms a solid called ’dry-ice’. There is no liquid phase. Conversely, warming dry-ice turns it...

Slip-casting

...liquid is drawn out of the slip, via a capillary action. A layer of solid slip (‘clay’) remains adhered to the walls of the mould. Once the required wall thickness of the casting has been achieved, the residue liquid is drained out of the mould. Once dry, the casting is removed from the mould...Stages of the slip-casting process: [Diagram to demonstrate 'Slip-casting'...

Why does it matter that the Sun's core rotates faster than the surface?

...liquids. From the S-waves and P-waves, we know the Earth has a solid core, a liquid outer core, and a solid mantle and crust. To work out what’s inside the sun, the ESA/NASA Solar and Heliospheric Observatory (SOHO for short) team has also used seismology to look at waves in the sun. In this context, it’s called helioseismology. However, you can’t stick an...

David Bowie: identity is creativity

...sang of his most famous creation, Ziggy Stardust in 1972. This might explain why the extra-terrestrial (whether human or alien) was an abiding metaphor he returned to from the early days of Major Tom in the song Space Oddity (1969) through his re-appearance in Pierrot costume on Ashes to Ashes (1980) and most recent embodiment in the video to his latest single Blackstar...
