I just hold the bottle by the neck and shake it back and forth horizontally and that usually loosens it up.
Wrong. They use thickeners. You should know that.
My Ph.D. is in rheology and material science. One of the craziest papers I ever remember reading was about the non-Newtonian behavior of frog tongues and saliva. I still think about this paper from time to time. There was a sequence of pictures showing a frog tongue (removed from the rest of the frog) lying on a table, and then somebody touching it with an ungloved finger and showing how sticky it was as they retracted their finger. What they won't get poor grad students to do...
Fascinating!
This graph is why I hate it when every video about a corn starch suspension says it's a "non-Newtonian fluid" as if that sufficiently explains it.
