One thing I may add is for an emergency lamp, use a can of crisco. Just add wick by submerging the wick in the center and shove to bottom. Wahla, an emergency lamp. Besides, crisco is made by the soap people, not for eating anyway?
Proctor and Gamble demonized the animal oil industry to promote their product. Like politicians do. Between the vegetable oil & crisco industry, America has the most unhealthest people in the world. Heart disease, diabetes, & cancer has run rabid due to the stuff we put in our mouth and call food.
