J's old shoes

Yesterday, after a bit of pestering from J, we sat on the front doorstep and cut open his beaten and now-too-small flashing shoes.  We pulled out the battery pack and sensor which, if flicked with the finger, made the lights flash still.  The wires between battery and lights have been exposed, but it's still attached to the shoe, and you can see where the battery used to fit under the heel.  We plan to bring it to his preschool for share day next week.
