Hidden message experiment with invisible ink
It is an experiment that is both surprising and extremely fun… Making invisible ink is actually extremely easy. Moreover, all of them can be made from materials at home. There are two methods for invisible ink, one is lemon and the other is milk. These two materials are normally colorless, but when they interact with heat, the oxidation process begins and turns brown, i.e. ink.
Let's gather our materials first: Paper, cotton swab, a heat source (can be a lamp or a stove) and milk or lemon.
How is it done? Put lemon juice or milk in a glass, dip a cotton swab in it and write your message on the paper. Let the paper dry. Your secret message is ready. After drying, hold the paper to the light or the stove and the message will begin to appear. If you iron on the paper with the help of your mother, your message will also appear.
TÜRKÇESİ
Görünmez mürekkeple gizli mesaj deneyi
Hem şaşırtıcı hem de son derece eğlenceli bir deney… Görünmez mürekkep yapmak aslında son derece kolay. Üstelik tamamı evdeki malzemelerden yapılabiliyor. Görünmez mürekkep için iki yöntem var, biri limon diğeri ise süt. Bu iki malzeme normalde renksizdir ancak ısı ile etkileşime girdiklerinde oksidasyon süreci başlar ve kahverengiye döner, yani mürekkebe.
Önce malzemelerimizi toplayalım: Kağıt, pamuklu çubuk, bir ısı kaynağı (lamba ya da ocak olabilir) ve süt ya da limon.
Nasıl yapılır? Limon suyu ya da sütü bir bardağa koyun, içine pamuklu çubuğu batırın ve kağıda mesajınızı yazın. Kağıdı kurumaya bırakın. Gizli mesajınız hazır. Kuruduktan sonra kağıdı ışığa ya da ocağa tutun, mesaj görünmeye başlayacaktır. Kağıdın üzerine annenizin yardımıyla ütü basarsanız da mesajınız görünecektir.

Cevap:
MATERIALS FOR THE EXPERIMENT:
• Red cabbage
• Hot water
• Glass bowl
• Glass
• Sieve
• Lemon salt/lemon juice
• Vinegar
• Baby shampoo
• Baking soda
• Soap powder
HOW DO WE DO THE EXPERIMENT?
• Cut the red cabbage into small pieces.
• Pour hot water over the shredded cabbage leaves.
• Wait until the temperature of the mixture reaches room temperature. We can see that the color of the water turns into a dark purple as time goes by.
• After the mixture has cooled, let's separate the cabbage leaves from the liquid part with the help of a sieve. So our marker is ready.
• Let's put lemon salt or lemon juice in a glass, let's drop the purple liquid we prepared on it. Has it changed color?
• Now the other items; let's color shampoo, baking soda and soap powder with purple liquid, respectively. What colors did we see?
WHAT HAPPENED AT THE RESULT OF THE EXPERIMENT?
Red cabbage juice is a marker that allows us to distinguish between acid and base. It creates different colors in the liquids on which it is poured, allowing us to understand whether that substance is an acid or a base. When red cabbage juice is poured on it, the substances that give orange, red and close to red color are acid, and the substances that give blue and blue color are bases.
