Solid Bubble Bath Recipe

1/3 cup of cream of tartar (available at supermarket)
1 cup of baking soda (sodium bicarbonate)
1 cup of sodium laurel sulfoacetate SLS (powdered foaming agent)
1/3 cup (more or less) of glycerin liquid
a few drops of water-based soap colorant or food color
any fragrance or essential oil (we used Juniper Breeze)
a mold (we used our small loaf mold)

Makes 18 ozs. Mix the dry ingredients in a bowl and add the colorant and fragrance a few drops at a time until the desired shade and scent are achieved. Mix in the glycerin liquid a little at a time until the mixture holds together in your hand. Transfer to your mold and press firmly into the mold. Unmold after about a hour and check for firmness. If the mixture crumbles, return it to the bowl and add more glycerin, then remold.

If it holds together when unmolded, cut into chunks or slices and continue to let dry on wax paper. May take overnight or longer to harden. Wrap in cellophane, tissue paper or store in container. Use within a month or two.

To use: Drop into running bath water and enjoy the bubbles!
