A vintage poster print from WWII. Housewives and butchers all over the country were mobilized to collect cooking fats for conversion to explosive ingredients.
One pound of waste fat equaled 1/10 of a pound of glycerine.
1/10 pound of glycerine equaled 1/5 of a pound of nitroglycerine.
1/5 of a pound of nitroglycerine equaled 1/3 pound of gunpowder.
1/5 of a pound of nitroglycerine equaled ½ pound of dynamite.
