Remember an interesting little test

Today, I saw an interesting little experiment in the book: separating pepper and salt. The book is so vivid, I look at it with gusto, the more I look at it, the more itchy, and finally decided to try it for myself.

I took about a quarter of a spoonful of pepper and about a quarter of a spoonful of salt from the kitchen and took a spoon from the sterilizer. The trial started!

I paint the tiger according to the cat. First, pour the salt and pepper in the spoon into a clean bowl and mix well with a spoon. Why stir it evenly? Because I hope to make the test more difficult. Then I took out a plastic ruler from the pen holder on the desk. You definitely want to ask me what I want to do, hey, if you want to know, then look down!

Next, I picked up the plastic ruler and rubbed it on the scalp until the ruler heated up, then quickly moved the ruler over the bowl with the pepper and salt. Ok? Why didn't you react? Touching the ruler, cold, squatting, should make the plastic ruler hotter, thinking, I use the ruler to continue rubbing on the scalp, hot, I quickly put it on again - ah! Successful! “噼里啪啦”, some particles were sucked up! So repeatedly, I managed to separate them apart. A closer look is that the pepper is sucked up.

“Why is the pepper sucked up?” I asked my mother who was always on the sidelines to test. "Because of static electricity." "Why is the salt not sucked up?" "Because the proportion of pepper is lighter than salt."

Science is amazing! I must study hard and contribute to humanity in the future!

This is really an interesting little experiment!
