Last week I put my granddaughter's cup full of water in my cotton shopping pod and it completely emptied out. It went through the daypack onto my car seat. My sound out is why has it left a stain on the form, when it was only sea?
maybe she'd be to local doctor and being old misplaced her urine preview cup with one of water?

:-D


Could it have mixed with something within the bag, or even the bag's color itself and then stained your form? What does the stain look like? Distilled water would not go away a mark , its is the minerals in the river that left the stain
Answers:    well when it leave results on material it is because the dye in the substance hasnt been set properly. Then as the water wash outwards it takes the dye with it that consequently collects as a dark ring where the hose down stops. this effect is called chromotography. however, when water leaves a mark off on windows or taps etc when it dries explicitly the residue of the salt and limescale in the sea
