Dough

kids sitting around a table carefully measuring flour and water etc. into a bowl and stirring dough
dough
They look at it pull it out stretching with a spoon and start to ad a "little" bit more ingreadients
dough
They stir it and stir it and add a "few" more ingreadients. It starts to get messy. It starts to overflow the bowl so they get a bigger bowl
dough
it gets messier and messier and bigger and bigger (maybe some kids sitting or standing on the table - with dough on them) They start adding less and less conventional ingreadients (one time Mariah made "cookies" in the kitchen without me and they had added pineapple leaves to it.) They are having a grande old time stirring it as it gets bigger and bigger. You realize the table is outside - some completely non-food items get added.
Dough - under each picture.
The dough gets humongous (and beautifully sticky) first in an old washtub, then a kiddie pool - just humongeous lots of things full of it! Wheal barrows, wagons soggy with it, etc.

at this point they may still have wooden spoons in their hands, but they are practically stirring it with their whole bodies. Stomping in it with their feet - all stuck together, etc. Robert munsch comes to mind. http://www.robertmunsch.com/books.cfm?bookid=29 (you should really read all his books! I love them!)
Dough - under each picture
They look around at it all and start building a house (maybe a castle or a really neat cool Dr. Suess house) out of it.
Dough - under each picture
Dough! Castle is all made.

(later, after baths, after castle has dried, or something)
once again all sitting around the table. They start measuring things into a bowl stirring -
dough.

(after picture)
the table was actually in their new house made out of "dough" - They are making little things out of bread dough cooking them in a n earthenware overn in their dough house and eating them. (with their mom)
