Very soothing. And impressive.
The following is a recipe I found here:
1.5 gal. hot Water
.5 teaspoon J-Lube
One tube (4.25 oz) Surgilube
1/4 cup Glycerine (99.5% pure or better)
Mix with Paint Impeller (without making foam)
16 oz. of Dawn non-Ultra (i.e., the cheap stuff)
1/2 cup of Dawn Manual Pot and Pan Detergent
For string, they suggest braiding 3 lengths of cotton butchers string.
