My friend E brought over her two children and the girl she watches today. I figured that we should try to do some kind of crafty/fun thing. I'd seen the Super Foamerator on Betz White's website awhile ago and was looking for an opportunity to play with foam myself. This seemed the perfect occasion. Although the kids didn't enjoy it for quite as long as these kids did, they seemed to have a good time with them.
Basically you take an empty plastic bottle (water, shampoo, salad dressing), cut off the end then secure a washcloth or piece of terry cloth fabric on the end with a rubber band. Dip first in water and then in a bowl of soapy water. We used dish soap. This creates a snake-like foam.
