Addressing only this very narrow point..

I don't see any value in an eutectic alloy.  Your goal is to dissolve the existing solder, which will immediately move the resulting alloy away from the eutectic point.  Unless I'm missing some effect, the ideal would be alloy that moves closer to the eutectic point when mixed with the existing solder.

I have actually reported this video to Youtube under the "Dangerous acts" category. They better take it down before some idiot (and there are plenty of them in the comments!) decides to emulate this fool.

I did the same thing earlier today. It’s totally reckless. I also took the liberty of using copy-and-paste to reply to many of the comments with a warning.

Shock:
I think he is using Gallium, you can see it solidify as it puts it on the top of the IC. I would think Mercury would be more liquid. If it's pure Gallium its boiling point is 2400C. Not sure how much of an effect it would have but it's corrosive to other metals so you would want to remove it thoroughly.
