soapsuds

Water and soapsuds blotched the broken floor, amongst which played two little boys, absolutely naked.

The colours produced from it are unchanged, they say, by warm soapsuds or light.

I splash in brief swift soapsuds, and go under a sudden heroic icy cold shower, and dry me with a scourging towel.

Economical Hint: A good imitation of soapsuds may be made by shaking a bottle of champagne and then opening the bottle.
