? First I prepared the following materials: rainbow candy, disposable plastic plates, water. The experiment began.
? The first step, I put the rainbow sugar in the disposable plastic disk. And in accordance with the order of red, orange, yellow, green, blue, purple arranged in a circle. Step two, add the right amount of water to the disposable plastic cup. Step 3, leave it there to sit for ten minutes. One minute, two minutes, three minutes ...... I held down the excitement, quietly waiting, almost ten minutes, I also called my parents over to observe the results of the experiment. The whole family looked to the disposable plastic disk, "Wow, success!" I shouted excitedly. Mom and dad said in unison "Congratulations!"
? The experiment was done, I thought: why rainbow sugar can summon a rainbow waterfall after adding water. Mom seemed to read my mind and said, "The principle of this experiment is that when the rainbow sugar touches the water, the edible pigment in it will dissolve in the water, and that's why you can see the rainbow waterfall."
? This experiment opened my eyes, as long as we pay attention in life, we will find many scientific mysteries Oh!
