Composition about a magic umbrella

I have a magic umbrella at home. You must feel strange after hearing this. How can an umbrella do magic? Then listen to me and tell you slowly!

In the morning, it was raining outside. My mother came over and said to me: "Xiaoxiao, go downstairs and buy some breakfast. Remember to bring your umbrella with you!" I took a purple umbrella and ran downstairs. When I got home after shopping, I was just about to do my calligraphy homework. Suddenly, my mother called out: "Xiaoxiao, come and see, this umbrella clearly had no pattern just now. Why did it turn into little flowers after sneaking around outside?" "Where is it?" I ran over to take a look curiously, ah! When did such beautiful little flowers bloom on the umbrella? Can umbrellas do magic? I observed carefully and finally solved the mystery. It turns out that this umbrella is made of a special material. As soon as it touches water, it will change into beautiful patterns.

Do you think this umbrella is magical?
