Tight wippen centers

[Mark Wisner]

It's the alcohol and water that does the work.  The soap is added to help
break the surface tension of the water to permit easier absorption into the
bushing felt (a surfactant).  The original recipe stated grated Ivory soap,
presumably because Ivory bar soap is more pure than others.
