ok so I did a science measurement with an Abena M4 and for some weird reason it would seem that water is heavier than urine which I don't understand.
Urine has all these chemicals inside and it's slightly less dense than water but water is a regular liquid and doesn't penetrate the cotton as well as urine does but water definitely makes it heavier. Urine penetrates the cotton but can hold alot more than water can.
It would seem to everyone there is no difference but to me I might have found a clue!
A regular Abena M4 can hold 65oz and I poured 2 Pints(32oz) 1 each(16oz) of urine and water into both Abenas and the water quickly spread all over while urine absorbed more quickly. I guess there is a Chemical in the Urine that would make it penetrate into the cotton than water but what is that Chemical? Does anyone know?
