Where to Buy Invisible Ink Glasses
Invisible ink is a way of writing secret messages that can be read only by people who have special glasses. These pens are useful in situations where you do not want strangers or roommates to read your private messages, such as writing down your social networking passwords. You can also use them to write down important information that you do not want anyone else to see, such as your address or phone number. These pens are usually made of clear plastic or paper and have a special invisible ink.
In invisible ink the chemical that is used to make the message visible is not revealed until it has been subjected to certain conditions. These conditions can range from heat to a particular light. These chemicals are often hidden in small areas of the message, which appear as scratches or marks. They may be written in a coded form or printed as part of an image, such as the yellow dots that many printers print on their prints to record the printer’s serial number and date of printing.
There are many invisible-ink pens on sale, including toys that come with a pen decoder to reveal the invisible parts of text or images. Invisible ink is also used to mark cards so that only others can see them. Some of these pens look like regular pens while others have two tips: one for marking and another for developing the ink.
