How much as a child we read adventure books about Tome Sauer, Electronics, Timur and his team. How loved these fun and mischievous boys. Well, who did not imagine himself a hero of books, pirate or spy? They played war guys, hide and seek, catching, Cossacks-robbers. Having matured, we began to forget how cool to preserve the genuine and radiant joy of the child. In this article we want to offer you to plunge into our barefoot childhood and make invisible inks at home. It is necessary to attract your kids, brothers, sisters to this fun process. The larger the people, the fun process.
Ink invisible
So, we will do ink, but not simple, but invisible! Interesting? Then we prepare everything you need.
We will need:
- Half of the Big Lemon;
- water;
- tea spoon;
- soup plate;
- cotton swabs;
- paper;
- table lamp.
After everyone was prepared, proceed to our "chemistry." Singing lemon juice and add one teaspoon of water into a deep plate. Pretty mix the water with lemon juice and plunge the cotton wand in the mixture. Now write your message on white paper, wait until the message is dry and becomes completely transparent. And now the most interesting. To read this message, you need to heat the paper under the table lamp, and it will show a message.
How did it work? Since juice is a "consequence" of organic chemistry, then one of its properties - with increasing temperature to produce a brown shade. Then diluted with water so that our message instantly dried and disappeared from the field of view.
Second way
This time we will bypass without lemon, but we promise that the effect will pleasantly surprise you.

So, we will need:
- gauze;
- grater;
- Young onion, one small head;
- paper;
- water;
- soup plate;
- teaspoon;
- table lamp.
Recipe
Sattail on a small grater one head of a young bow. Now take the marblee and put in it grated onions, squeeze juice. Mix the resulting juice with water, the proportion of one to one, stir in the deep plate. Write the text and let die twenty minutes. Now bring to the desk lamp, wait a minute and read the planned one. Luke Juice This experience can be replaced with orange juice, as well as milk. Milk always get good ink.
Option with soda
In our home "chemical laboratory", consider some more options. So, option from soda.
For this we will need:
- baking soda;
- toothpick or cotton wand;
- water;
- White paper.
Mix in equal proportions The composition of food soda and water. With a cotton wand or toothpicks, write text on paper using a mixed solution as ink. Let's dry the inscription ten minutes. Now you can view it, as in the previous ways, under the lamp. And you can experience much more interesting. Take the black grapes and discourage the juice from it. Skin the juice all the white paper and wait five minutes. And, about a miracle, you will see a bright contrasting inscription, which appeared on your eyes.
For those who were seriously interested in invisible ink and adventure games, we should like the use of a huge range of various chemicals as a basis for mysterious data transmission. For such games, very many substances are suitable, but advanced spies simply need to remember the effects of acid.
Almost all invisible texts will you read if you apply an acid (for example, juice from lemon). Well, how did you conclude from the disassembled options, most letters are revealed when heated. So before going to the campaign, on a secret task or intelligence, be sure to take a source of light, heat and acid with you. Also before an important task, do not be lazy to run into the laboratory, because agents have already prepared magic drugs for you.

List of magical developers:
- a slide of washing powder;
- phenolphthalein (react with soda, due to which it manifests itself well);
- Apple vinegar or acid (react with red cabbage juice and manifests colorless ink);
- Cooking salt (to read the messages of silver nitrate);
- copper sulfate (need iodide sodium or ammonium hydroxide);
- Iron sulfate (react only with soda);
- Corn starch (for reading the iodine solution is needed).
So we disassemble the simplest and entertaining ways to prepare invisible ink. We hope that you have found a lot of useful information and now the impressions of the experiments will remain for a long time in memory.
