Do you have a newspaper clipping that you are saving? Here is a little science that will preserve that memento over the years.
Dissolve a Milk of Magnesia tablet in a quart of water. Let it stand overnight. Pour the mixture into a flat dish large enough to hold the newspaper clipping that you are planning to preserve. Place the clipping into the solution and press down with a wooden spoon until the paper is completely submerged in the liquid. Soak for one hour. Remove the clipping from the liquid and pat dry.
The chemistry behind this is a reaction between the acid in the paper and the magnesium carbide in the antacid. When the acid in the paper is neutralized, the paper will not turn yellow with age.
