Tornadoes come in many shapes and sizes, but they are typically in the form of a visible condensation funnel originating from the base of a huge storm cloud, whose narrow end touches the earth and is often encircled by a basal cloud of debris and dust.
Soda jerk. A soda jerk (or soda jerker) is a personâtypically a youthâwho operates the soda fountain in a drugstore, often for the purpose of preparing and serving flavored soda water or an ice cream soda. This was made by putting flavored syrup into a specially designed tall glass, adding carbonated water and, finally, one or two scoops of ice cream.
a reflected action or movement; the sum total of any particular automatic response mediated by the nervous system. A reflex is built into the nervous system and does not need the intervention of conscious thought to take effect. The knee jerk is an example of the simplest type of reflex. When the knee is tapped, the nerve that receives this stimulus sends an impulse to the spinal cord, where it is relayed to a motor nerve. This causes the quadriceps muscle at the front of the thigh to contract and jerk the leg up.
