Homemade bubble bath?
I was wondering if anyone has made any homemade bubble bath here. I've been looking at recipes online - Most of them are very similiar - they call for a bar of castille soap, shredded, a quart or so of water and some kind of essential oil or scent, and glycerine. It sounds good to me, but none of the recipes on various sites have said how much of this concoction you'd have to use in a bath to get bubbles. I would hate to make a quart of this if I had to pour half of it in the tub to get bubbles. Can anyone shed some light on this?
