The citric acid in Coke removes stains from china. • To remove rust spots from chrome car bumpers: Rub the bumper with a rumpled-up piece of Reynolds Wrap aluminum foil dipped in Coca-Cola. • To clean corrosion from car battery terminals: Pour a can of Coca-Cola over the terminals to bubble away the corrosion. • To loosen a rusted bolt: Apply a cloth soaked in Coca-Cola to the rusted bolt for several minutes.

  16. Coke #1     the active ingredient in Coke is phosphoric acid. It will dissolve a nail in about four days. Phosphoric acid also leaches calcium from bones and is a major contributor to the rising increase of osteoporosis. #2.   To carry Coca-Cola syrup!

  23. Healthy Weight Management An average person needs 2500calories to have enough energy to perform daily tasks. Any additional calories taken beyond those required for their BMR can be stored asfat_. 1 pound = 3500calories If a person wants to lose 1 pound, they must BURN or use 3500calories. If a person wants to gain 1 pound, they must CONSUME 3500extra calories above their BMI. The healthiest way to lose weight is to lose 1 to 2 pounds a week.
