Absorbency of various cotton, bamboo, hemp, & Microfiber inserts

My method for testing absorbency is you get a 4 cup glass measuring cup and fill it with more than what I expect something to absorb (or a whole number that is easy to remember) then pour over item in a bowl - "slowly" in case there is no reason to pour it all.

Some items like prefolds and flats need to be moved around a little or refolded differently sometimes.

I do that until it seems that the item is saturated. Then I hold up over the bowl (or the measuring cup) and see if it drips at all. Hold it there until it's at a very slow / no drip state.

I pour anything left in the bowl in the measuring cup and check amount. Then subtract.
