In the tub
Swirl fills take longer to make than flat colours, which is why most slime is one shade. The pattern is the point here: it photographs well, and it gives the first pull something to ruin.

Two swirl tubs rather than two flat colours. Each one is filled in ribbons, so the pattern is there before anybody touches it.
Texture, scent and the sensible way to live with it.
Swirl fills take longer to make than flat colours, which is why most slime is one shade. The pattern is the point here: it photographs well, and it gives the first pull something to ruin.
After a few minutes of folding the ribbons marble together, and the tub settles into a single mixed shade that is usually prettier than either of the originals.
Press the lid down after every session and keep it out of sun and off a radiator. Air is what shortens a tub's life; age is not. A stiff rim kneads back into the soft middle, and a tub that has set through is finished — water and lotion make it worse rather than better.
