As you can see it foams up from the very start.
There is also pink kaolin clay in there, which adds a pretty hue to your tub water.
The tub is filled and as you can see it foamed up quite a bit. I put 2 capfuls in the tub.
As it drains it does leave some clay residue, but....
A cup of water swished at the end left the tub clean with no scrubbing.
My skin really liked this, it didnt leave me irritated or red in any way. This is comes in a glass jar and sells in the store for $12.00.
