new discovery in science of blowing up stuff

Alkali metals can react explosively with ​water and it is textbook knowledge that this vigorous behaviour results from heat release, steam formation and ignition of the ​hydrogen gas that is produced. Here we suggest that the initial process enabling the alkali metal explosion in ​water is, however, of a completely different nature. High-speed camera imaging of liquid drops of a ​sodium/potassium alloy in ​water reveals submillisecond formation of metal spikes that protrude from the surface of the drop. Molecular dynamics simulations demonstrate that on immersion in ​water there is an almost immediate release of electrons from the metal surface. The system thus quickly reaches the Rayleigh instability limit, which leads to a ‘coulomb explosion’ of the alkali metal drop. Consequently, a new metal surface in contact with ​water is formed, which explains why the reaction does not become self-quenched by its products, but can rather lead to explosive behaviour.

So what’s wrong with a parody of black metal done by a parody black metal band? Well, obviously, the MUSIC. Assuming you agree it’s even music at all.

This video fixes that one remaining problem.

I may have posted this before, but I don’t care.
