Alkali metals react in water because of coulomb explosions:

The explanation was only discovered this year.
- pdkl95 11y agoThat's the video from before they published (which is still interesting). There is also a more recent video[1] (post-publication[2]) that covers how they got the data (which supports the coulombic explosion hypothesis). While it is mentioned at the end of the newer video, I highly recommend watching the 500fps footage[3] of a drop of NaK burning (just before it explodes) on the top of water. There is a striking color change as it starts to interact with the water, and right the NaK explodes... the metal turns completely transparent.

- vanderZwan 11y agoCool video, but it is from 2013. I guess you mean confirmed this year? Because the top comment links to this: http://www.nature.com/nchem/journal/v7/n3/full/nchem.2161.html http://www.nature.com/nchem/journal/v7/n3/full/nchem.2161.ht...
