Simple Games on a Rainy Day

So it is raining.... again... and I am trying to come up with some new and exciting activity to keep my crazy, I mean active, three year old entertained, when he asks to play in the kitchen sink. He grabs his stool and announces that he is going to make waffles in the sink.  I go with it, asking what kind of waffles, maybe blueberry?  Pretty soon he is pouring water back and forth between a mason jar and a measuring cup and using a wooden spoon to stir his waffles.  This lasts about 20 minutes then I add ice to the picture and he is off again.  Sometimes I have to be reminded how simple it really can be!
