With invisible ink you write any words and draw different drawings. But then they will disappear! Surprise your acquaintances at a party or birthday, write a secret note to a friend or make an interesting experience with children. There are many ways to manufacture invisible inks.
We do invisible ink from lemon juice
Squeeze the juice from the cut lemon into the bowl. Add a little water and stir. Test our ink:
- take a sharp little wand or thin brush. Well, if there is a pen with a pen;
- slope the wand in the ink and write something on a white sheet of paper;
- let the inscriptions dry - the message will become invisible;
- find an invisible inscription on a sheet with an iron, ink will begin to manifest.
You can hold a sheet of paper above the burning candle at a distance of 10 cm - a similar result will be released. The inscription will be brown. The same dark inscription from invisible ink after heating will result in the use of apple, onion and other juices with a large content of acid.
We make invisible inks from milk
Pour a slightly milk into a cup. Perch a wand in milk, and we write something on paper. Let the milk dry well dry on a sheet. To read the inscription, heat the sheet on the light bulb, above the candle or endure the iron.
Make an invisible ink from starch
Ink cooking process Next:
- connect 2 parts of starch with one part of the usual water;
- heat the resulting hobster on slow fire, stirring all the time;
- let the Clastier cool;
- write a cotton or sharp wooden wand cooled word ink on paper.
For the manifestation of words, lubricate a leaf with an aqueous solution of iodine. Paper paints into light purple color. And the words that will manifest from ink will become dark purple.
We do invisible ink on an old Chinese recipe
Ancient Chinese emperors enjoyed a rice decoction for secret messages. Weld a thick porridge from rice. See that rice does not absorb all the liquid. This water and use as invisible ink. Write a message on paper. For the manifestation of inscriptions, smear the water with an aqueous iodine.
We make invisible inks from food soda
Prepare:
- water;
- grape juice;
- food soda.
Water with soda connect in proportion one to one. Pretty mix them in a bowl and you have an ink based on soda. Apply them on paper, but for the manifestation of a secret message, heating will not help. Use grape juice. They dip the tassel in juice and paint the paper until the inscription appears.
Useful advice
To heat the sheet instead of iron, candles or lights can use the oven. Place a secret message in a hot oven and wait a few minutes to show a message. Invisible inscriptions manifest themselves on a leaf when heated because the ink substance is charred faster than paper.
Do not forget about the safety technique if you show the message on the open fire! Prepare a saucepan with cold water. In it, you put off the leaf, if it is inappropriate lights up.
Choose any ink recipe and surprise familiar or play spies. Even the secret agents of Ivan Grozny wrote their messages to the tsar onion juice, and no one could read the message.
