Shaving cream used as snow. The most fun and messy thing you can do for a dollar. We made roads and drove the cars through the snow. The shaving cream cleaned the table and the room smelt so good the rest of the day.
I supervised them all while they added white ivory soap snow flakes with the shredder to help our experiment turn into snow. I remember when I first was living on my own and use to buy this soap. Oh gosh the smell is terrible and reminds me of back then, but the kids seemed to not mind.
