So, here's what you do. Take your desired container with airtight and watertight lid (I used a peanut butter container) and fill it 3/4 of the way with coarse kosher salt. Pour in oil, I used baby oil, Dani uses lavendar scented baby oil but I don't like the smell; and stir adding a little at a time until the mixture resembles the texture of wet sand. Voila!

Be careful, the tub may get slippery from the oil. Also don't use on freshly shaved skin (ouch!) or on any spots that are especially sensitive.
