You may write clever messages and also have a large amount of fun by using a secret ink that only you know how to make visible.
To produce your ink, use only harmless solutions. About the trail, you can always carry your bottles and writing materials along so that they will likely be handy
Writing with secret ink to ensure outsiders cannot read your message isn’t as simple as you may assume. If you are using a pointy penpoint your writing won’t be as secret as you like, for the point will scratch the paper slightly each and every stroke. Set up scratches are not visible for the human eye alone, they may be seen with a magnification glass.
So you should work with a smooth, broad penpoint. However, this too has a drawback. The writing fluid leaves a slight shine around the paper. If your strokes are far too wide, the writing will probably be perfectly legible in the event the sheet takes place at an angle to the light.
The best option writing tool is a soft stick of wood sharpened to a degree. Additionally, you can work with a toothpick.
Write on light-colored paper which is not too thin, because thin paper wrinkles where it has been moistened. This wrinkling can betray the use of invisible writing and also allow it to be legible. The advisable thing is a great, hard-surface paper. Cautious writers never use blank sheets for their messages. Instead, they write some message with regular ink or pencil which will confuse the outsiders. Chances are they’ll write the truly important message relating to the lines with invisible ink. This diverts the attention of anyone not in about the secret from the possible traces from the dried invisible ink.
In order to be really clever, combine the invisible ink with the normal writing. For instance, write a regular message that’s confusing or meaningless. Then, using invisible ink, cross out some letters from the false message or convey a dot over or under these letters in a way to make them disclose the really important message.
You can create your invisible ink beyond any one of the following liquids:
Freshly squeezed lemon juice
Sugar and water
Milk thinned slightly with water
Water through which eggshells are already soaked during their visit
After these fluids dry, they become invisible. To really make the writing reappear, carefully warm the sheet by holding the written side over a flame. Lo and behold!-the writing will probably be visible within a faint brown color.
