I should have taken pictures to enhance the description, but I forgot and will add them to the thread, the next time this happens. Every once in a while, after the usual shaking, I notice the liquid in the container, instead of the usual various shades of brown, it's almost clear. So clearly, I know we have a problem. So I open up the ball. Normally the powder is soaking wet, with plenty of liquid inside and free flowing. But for the times I get the clear liquid and open the ball, it's hard and damp and clumpy on each end, and in the middle there is actually a little powder that's totally dry and obviously been untouched by water. In addition there's also usually few round little balls of kava, that are also damp and hard. Now, I know what your likely initial response to this would be - that you may assume I'm filling the ball with too much powder. And that would seem logical. But it's not the case. I am very consistently exact when measuring my powder. It's either 2 exact tablespoons, or I just fill up to a certain line, that equals that amount. Either way, it's the same amount every time. So, basically my measurements are very consistent - yet the results are highly random, as sometimes this phenomenon happens for no apparent reason. And it's really frustrating, because it means I've wasted that time shaking, and in order to "fix" the problem that particular time, I have to remove the damp powder completely, and uniformly re-arrange it back into the ball. And since I'm super germ-conscious, and wash my hands every time I open the ball and mess with the powder, it means I also have to wash my hands again, before "fixing" this. So, what is causing this to just randomly happen, when my method is so consistent ?
