Knowing YT they will kindly ignore your report or if they don't, the video will be reuploaded next day together with a short commentary about New World Order taking down videos to sell more hot air stations.

You do it because you know they don't care about your opinion :P

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.

At the end of the video he says it’s mercury and calls it “harmless”.

And there's an Eevblog video for that too....

The second half of the video is muted for me. But as I said it doesn't look like Mercury unless it has already been turned into an alloy. Could be a Gallium Tin alloy that can melt around 25-28C. Anyway nice screwdriver tip he is using. :)

It is certainly not gallium, gallium isn't liquid below 29C or so (you can see it is well liquid when he is picking it up from that tin). Unless his room was very hot, there is no way it would work like that - it would be either solid or semi-solid until heated up.

He also mentions several times in the comments it is mercury - which is apparently easy to get in India or where he is from. He mentions in the comments that it can be easily bought in stores (it is used in traditional Indian ayurveda medicine, together with lead - yay). Gallium isn't commonly sold as it has little domestic/traditional medicine uses apart from thermometers.
