It is possible to write clever messages this will let you lots of fun using a secret ink that only you and your friends understand how to make visible.
To produce your ink, only use harmless solutions. Around the trail, you can carry your bottles and writing materials with you so they will be handy
Writing with secret ink to ensure that outsiders cannot read your message just isn’t as simple as you may assume. If you use a clear, crisp penpoint your writing won’t be as secret as you wish, for that point will scratch the paper slightly with each and every stroke. Set up scratches aren’t visible to the human eye, they are often seen having a magnifying glass.
So that you should use a smooth, broad penpoint. However, this too has a drawback. The writing fluid leaves a slight shine on the paper. If the strokes are far too wide, the writing will probably be perfectly legible once the sheet takes place in an angle for the light.
The best choice writing tool is often a soft stick of wood sharpened to a degree. Or you can make use of a toothpick.
Write on light-colored paper that isn’t too thin, because thin paper wrinkles where it has been moistened. This wrinkling can betray the existence of invisible writing as well as help it become legible. The advisable thing is a good, hard-surface paper. Cautious writers never use blank sheets for his or her messages. Instead, they write some message with regular ink or pencil which will confuse the outsiders. Then they write the really important message between the lines with invisible ink. This diverts the interest of anyone not in on the secret from any possible traces of the dried invisible ink.
If you want to be really clever, combine the invisible ink with the normal writing. For example, write a consistent message which is confusing or meaningless. Then, using invisible ink, cross out some letters from the false message or put a dot over or under these letters in a way include them as disclose the truly important message.
You may make your invisible ink out of one of the following following liquids:
Onion juice
Freshly squeezed lemon juice
Brine
Sugar and water
Milk thinned slightly with water
Water through which eggshells are already soaked stay
After these fluids dry, they become invisible. To make the writing reappear, carefully warm the sheet by holding the written side over the flame. Lo and behold!-the writing will probably be visible in a faint brown color.
