THE NORTH RIDING PROJECT

Where destruction is involved, the weapons of the citizen-saboteur are salt, nails, candles, pebbles, thread, or any other materials he might normally be expected to possess as a householder or as a worker in his particular occupation.  His arsenal is the kitchen shelf, the trash pile, his own usual kit of tools and supplies.  The targets of his sabotage are usually objects to which he has normal and inconspicuous access in everyday life.

If you can accumulate sugar, put it in the fuel tank of a gasoline engine.  As it burns together with the gasoline, it will turn into a sticky mess which will completely mire the engine and necessitate extensive cleaning and repair.  Honey and molasses are as good as sugar.  Try to use about 75-100 grams for each 10 gallons of gasoline.
