I believe all of you have ever seen a rainbow. Now let's make our own rainbow even when it's not raining, as long as the sun is shining.
Before making it, please prepare materials, such as plastic tray or bowl, water, a piece of paper and mirror.
Now, let's make it step by step. I'll gide you. First of all, fill the tray with water, then put it in a sunny place, such as on a windowsill or outside. After that, stand the mirror in the tray so the sun can shine through the water onto the mirror. Then, hold the paper above the tray. Tilt the mirror until you see a rainbow on the paper.
Nice rainbow isn't it?
