The principle of color-changing flowers is one of the mysteries in this ever-changing world.

A color-changing flower, as its name implies, is a color-changing flower, but you should never treat it as a plant. Color-changing flower is an experiment designed according to the principle that acid and alkali change color when meeting purple cabbage.

1. First, fold a crumpled piece of paper into a flower. Spread a layer of white vinegar evenly on it with a brush.

2. Cut the crumpled paper into two leaves, put a layer of alkaline water on it and dry it.

3. Stick the dried flowers and leaves on a paper stick and make several more in turn.

4. Sprinkle the prepared purple cabbage water on it. The white paper flowers look like red flowers and green leaves.

Therefore, we can draw the conclusion that acidic substances turn red when they meet purple cabbage water; Alkaline substances turn green when they meet purple cabbage water.

In real life, you can also apply this knowledge.

Bamboo likes alkaline soil. If acid rain falls, there will be a lot of casualties. Therefore, applying some alkaline fertilizers to the bamboo forest can ensure the vigorous growth of bamboo.

Look, you can find knowledge anytime and anywhere in your life.

I hope it helps you!
