Car Troubles...

    This old prank was probably first tried on model-T Fords.  Lever off a hubcap.  Place four or five steel ball bearings into it.  Replace the hubcap.  When the car is driven, the wheel makes a rattling sound until centrifugal force holds the marbles at the rim.  The startled driver will hear a noise like nails rattling in a rusty can when stopping or starting the car.  A real belly-splitter, eh?
