Many a true word said in jest.
When I was doing demolitions in the army, detonating cord was white
for live and a blue for training/dummy. However as a lot of army stuff
is done at night, or in poor light, the cord was marked with projecting
lengthwise ridges in training/dummy and smooth if live.

So you could tell if you were dealing with stuff that could go BOOM or
stuff that was just plastic cord, by feel alone.
