Apple association

Apple is my favorite fruit. The round red apple bites down, crunchy, sweet and sour, very tasteful. Apples are delicious and nutritious. It not only nourishes the stomach, but it also enhances immunity. As the saying goes: "Eat an apple a day, don't know where the hospital door is?" This is the truth.

Apple is not only delicious, but there are two big secrets hidden in the apple. do you know? The peeled apple will change color. Because the oxygen in the air reacts with a substance called an enzyme in the apple, it changes color; do you know? There are still stars in the apple! When we cut the apple vertically, we won't find any difference. When we cross the apple, the miracle happens. You will find stars in the apple! Why are there stars? Because we cut the direction differently, the results we see are different.

Therefore, as long as we are good at observation and good at thinking, we will find more secrets around us!
