This made me really uncomfortable, like I was someplace in nature I had no business being, but it was also fascinating and wonderful. I watched the whole thing and it went by way too fast, the same thing never happened twice and a lot of the liquid movement was straight up beautiful.

This is awesome, but I read the title as Saturn VS Hydrogen tank which would have also been awesomer.
