The novel part happens when the drop of metal turns black and then transparent and then explodes. Harry https://www.youtube.com/watch?v=BIGMfai_ICg Invisible Metal (better than transparent Aluminium!) Published on Apr 22, 2014 Weird, weird shit happens when alkali metals such as sodium, potassium and so on react with water. The bottom line is that noone has looked at this sort of thing in detail for about 100 years. It is therefore not unsurprising that no one was crazy enough to try to get close enough to these explosions to see if anything interesting was happening..oh boy does interesting stuff happen.
