That&#x27;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).<p>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 <i>completely transparent</i>.<p>[1] <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=LmlAYnFF_s8" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=LmlAYnFF_s8</a><p>[2] <a href="http:&#x2F;&#x2F;www.nature.com&#x2F;nchem&#x2F;journal&#x2F;v7&#x2F;n3&#x2F;full&#x2F;nchem.2161.html" rel="nofollow">http:&#x2F;&#x2F;www.nature.com&#x2F;nchem&#x2F;journal&#x2F;v7&#x2F;n3&#x2F;full&#x2F;nchem.2161.ht...</a><p>[3] <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=BIGMfai_ICg" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=BIGMfai_ICg</a>
