How to make invisible ink. This was the step by step process:
After the steps, I got a pipette to stir the solution for a few minutes, then I got a drop of the red liquid and put it on some paper. After a while, the ink started to disappear, it only left a moist trail behind. Today, I learned that this invisible ink lab connects to ocean acidification because we are learning about acidics and how they are used in our world. All acidic items are used in different ways, but all of them still do the same thing, they all break things down. After the lab, I discovered how invisible ink works. Invisible ink is acidic, meaning it can break down certain things, such as paper. We can tell by using the pH indicator. a tool use to tell if something is neutral, acidic, or basic Once the ink comes into contact with the paper, the ink starts to break down that area, making it weak. You then can’t see what was written anymore, meaning it turned invisible. Invisible ink is used for many possibilities, such as hiding secret messages. Invisible ink is a great way to keep things hidden from others, and showing people certain things you don’t want other people to figure out.
