Piston-to-Valve Clearance (#11)
Someday you could find yourself at the track, out in the field, or at home in your garage needing to check piston-to-valve clearance after a cam swap or cylinder head change and there is no clay available.
No problem, go buy yourself a Tootsie Roll, and after it sits in your pocket for 20 minutes or so it should be soft enough to use.
