It is, after all, a part of nature.

Aaaand thats why you don't bring mercury on air planes.

Could be interesting - if properly explained, but what an ARROGANT AND STUPID idea to post such a nice Demonstration without any PRECISE CHEMICAL Explanation of What's happening here Why !!! Actually this posting is STOLEN from Theodore Gray's Youtube Demonstration "MERCURY ATTACKS ALUMINIUM", where is at least explained, whats Happening, although not why...:
A small amount of mercury amalgamates itself into an aluminum I-beam and destroys it from within. Gallium scratched into the surface allows the mercury to penetrate the protective oxide layer that normally surrounds anything made of aluminum.
This is a time-lapse video, the action takes about two hours in real time. The powdery oxide is falling off, what you don't see is a significant pile of it building up underneath.
This is the original Pop Sci article on the topic:

Actually, on the Site quoted by Theodore Gray on Youtube, http://periodictable.com/PopSci/2004/10… there is at least given a simplyfied Explanation of the Chemistry behind this Mercury attack... READ IT THERE, I YOU DO NOT WANT TO STAY COCKTAIL HAPPY STUPID AND IGNORANT!
Actually the deeper Explanation of this phenomenon, which refers to the concepts of chemical reactivity, Electronegativity, the Position of an element in the Periodic System of the Elements which reflects the Electron Configuration of the Electron Hull of the Elements leads to the rather fundamental Question: WHY IS SOMETHING HAPPENING AT ALL? The answer in this case is: Because it's possible (means: the Energy-Barrier to "activate" or initiate this reaction is not too high - meaning in this case, there ARE some weak, "open" spots in the otherwise rather solid Protection Layer of the Aluminium Metall built up spontaneously by Oxydation in Air. And because the final "Product" of this Reaction, a kind of an intermetallic Mercury - Aluminium Alloy (called Amalgam) or even intermetallic Compound, represents a lower over all Energy Cntent than the Sum of the Energy -Contents of the Mercury and the Aluminium alone. The fact, that this Reaction normally never goes spontaneously in the oppsite direction, meaning, that the Aluminium and the Mercury spontaneously separate from each other - (or at least, that this has never been observed so far) - is related to the principle of ever growing entropy... and therefor finally with the (fare) end of our cooling universe (If it does not somehow all starts over again - or an "allmighty Force"like God intervenes in time...)

It's at best sad and silly and at worst arrogant, stupid and deeply misanthropic to show such (stolen or self produced - does'n matter) scientific demonstrations only for their sensational Appeal without giving the interested spectator any Chance or hint to understand it! Since and scientific phenomena are NOT some Magicians tricks! They may - like those - be uesd to catch the curious spectator's eye. But then, - other than a magicians tricks - they MUST be explained or at least interpreted!
