Playing in the Mud On Purpose

Imagine their surprise when we purposefully played in the mud this week!  We have been studying Mesopotamia and Ancient Egypt.  We learned all sorts of interesting things last week and one was they had to make their own bricks out of mud and straw.  So I found an old shoebox and the shovel and we dug up the backyard.  Well, it is more clay than mud here but they got the idea.  Jack and I really got into it while Spencer held the hose adding water for us.  Then he went and found a stick and used that to stir because he was NOT about to stick his hands in that mud!  And then Spencer carefully held the hose for us to rinse off our hands.  We are waiting for the mud brick to dry so we can peel off the cardboard and see our finished product.  Fortunately, it is supposed to be 100 degrees here Monday.  Yes, that is 100, not a typo.  I'm thinking by Tuesday, our brick will be completely dry!  How many bricks should I have them make????!!!!!   Or I should say, "How many holes are we allowed in our yard?!!"
