     These are instructions for making invisible ink using baking soda.

     Difficulty: Easy

     Time required: A few minutes

     What you need:

     Baking soda

     Paper

     Water

     Light bulb

      Paintbrush

     Measuring cup

     Purple grape juice

     Here's how:

     There are at least two methods of using baking soda as invisible ink. Mix equal amounts of water and

baking soda.

     Use a paintbrush to write a message onto white paper, using the baking soda solution (溶液) as "ink".

     Allow the ink to dry.

     One way to read the message is to hold the paper up to a heat source, such as a light bulb. The baking

soda will cause the writing in the paper to turn brown.

     The second way to read the message is to paint over the paper with purple grape juice. The message will

appear in a different color. Tips:

     If you are using the heating method, avoid igniting (点燃) the paper.

     Baking soda and grape juice react with each other in an acid-base (酸碱) reaction, producing a color

change in the paper.

     Grape juice concentrate (浓缩物) results in a more visible color change than regular grape juice.
