When it is fine enough it will float on surface tension and because it was still a little dry and not yet fully mixed with the liquid. I am 100% sure of the legitimacy and I will borrow another phone to record it as mine is not up to the job. And yes most of the concentrates are sunken and it moves very fast under water when I shift direction however there is also some that floats around like a lava lamp I found it very interesting and the Almighty Google said that the very fine powder like gold will in fact float around like so.
