Yes, this one is fake, but I've seen a couple of videos from two different hobbyists that had something similar happen with large containers full of platinum (half as expensive as gold these days) in solution.

In the first case, his cat broke the container and the liquid penetrated the ground and was lost. In the second case, I don't remember how it was spilled, but it ended up getting soaked into a large amount of cardboard that was covering the floor. The guy incinerated the cardboard and then extracted the metal from the ashes by getting it back into solution. Most of the platinum was recovered and it was amazing to watch.

The first YouTuber is Cody's Lab and the second one, who only works with precious metals on his channel, is Sreetips.
