non-toys... the best toys

The kids are showing me again just how crazy I am to buy expensive toys.  Today the item of the day is a large stainless steel mixing bowl, which they are spinning like a top, rolling across large expanses of living room and wearing on their backs as a "turtle shell".  The best part (in my opinion) is when the bowl stops and makes a sort of gong-like sound and both kids shout "Too loud!"  The dog is unsure what to make of this.
