How do you make magic ink?

Answer 1

Making disappearing ink requires some chemical compounds that may not be readily available at home. Making blue disappearing ink requires .10 grams of thymolphtalein, 10 milliliters of ethyl alcohol, 90 milliliters of water, and 20 drops of 3M sodium hydroxide (or 10 drops of 6M sodium hydroxide solution.) Start by dissolving the thymolphtalein in the ethyl alcohol. Then stir in the water. One drop at a time, add the sodium hydroxide until the solution turns dark blue. Store the ink in a sealed container until you want to use it.

Answer 3

Magic ink can be made using chemical solutions that are invisible until activated by heat, light, or a specific chemical. Common methods include using lemon juice or vinegar as ink and revealing the message by heating the paper. Another method involves mixing water with a solution of iron sulfate and tannic acid, which appears invisible until activated by a developer solution containing gall nut extract.
