Making Invisible Ink
-This simple experiment is great for young kids, but must be conducted with adult supervision because it involves using the kitchen stove. Invisible ink has fascinated kids for generations.
-You might think that it would be difficult to make, but it’s not.
-All you’ll need for this experiment is some milk; some white paper; a clean cotton swab or small, clean paintbrush; the kitchen stove; and help from an adult.
-All you need to do is, using the brush or cotton swab, write your message with milk on the paper. Don’t use a lot of milk and soak the paper. Use just enough to make a thin coating.
-Once you’ve finished writing, ask the adult who’s helping you to turn on the kitchen stove to a low heat. Very carefully, using kitchen mitts , hold the paper about a foot above the warm burner. If you don’t see results, you may have to make the burner a little hotter.
-Do not, however, hold the paper low over the burner. As the paper heats up, your message will-become brown and you’ll be able to see what was written
