Ok so hit your local dollar store, grocery story, walmart, or perhaps your bathroom cupboard and get a can of shaving cream (not gel). This can can provide entertainment for as many as 10 kids at a time! If you have a glass, marble, or laminate table squirt it right in front of the kids and let them get creative! It is just like fingerpaints with none of the mess. The cream will wipe right off of their clothes without leaving a stain and it will clean your table and leave behind a nice fragrance! If you have a wood table then you could always pull out an old plastic table cloth and spread it over your table or take it outside and put it on the ground and let them go at it!
