One day, I read in a science book that sugar water can make invisible ink, so I started an experiment driven by curiosity.

I mixed the sugar water first, dipped my brush in sugar water, and wrote the word "open the door" on the paper. Then I dried the paper door. There's nothing. I began to doubt this book. Finally, I burned it with a lighter and saw a light brown word. When I saw it, I was ecstatic and immediately said to my mother-in-law who was watching TV: "Mother-in-law, come quickly, I will do magic for you!" "

So, I took another piece of white paper, wrote the word "mother-in-law" on it, dried it with a hair dryer, and there was nothing left. I quickly asked my mother-in-law: "Do you believe it or not? I can write the word' mother-in-law' with fire without a pen. " Mother-in-law shook her head, obviously not believing it.

I found a lighter to bake for a while, but it took a long time. I accidentally burned the paper. My mother-in-law smiled. I was a little anxious and said, "Don't be proud, wait a minute." I wrote those two words on a piece of white paper and dried them. This time I just baked them for a while, and the words appeared. I smiled proudly, and my mother-in-law quickly took the paper from me and read it over and over again, but she just didn't understand.

Little friends, do you understand? If you don't understand, let me tell you something!

Because after writing words on paper with sugar water, glyphs and patterns will disappear after drying, and after baking, glyphs and patterns will appear light brown due to dehydration of sugar.

Use your head and think about what other liquids can be used as invisible ink besides sugar water.

Science is magical!
