(KTEN) — In this week's Braindrop segment, Ms. Glidewell's first grade class in Wilson, Oklahoma, is asking: "How are rainbows made?"

We're breaking down the science via explainer and experiment. 

Here's what you'll need to do the experiment in class or at home:

  • a napkin or paper towel
  • markers with rainbow colors (red, orange, yellow, green, blue, indigo, violet)
  • two glasses of water
