This is the usual method for drying such things as vegetables, meat and fish. Liquids such as milk, coffee, tea, soups and eggs may be dried by pouring them over a heated horizontally round steel or by spraying them into a place through which hot air passes. Dried foods take up less room and weigh less than the same food packed in cans or frozen, and they do not need to be stored in special conditions. For these reasons they are invaluable to climbers, explorers and soldiers in battle, who have little storage space. They are also popular with housewives because it takes so little storage space.

A total of 63 (37) of the 65 sightings(38) along nearly vertical faults. The researchers suggest that along these faults, the stress of rocks (39) against each other produces electrical charges, which can travel upward and interact (40) the atmosphere to create light.
