How to Flip a Rainbow

Materials:

White Paper
Markers (We love sharpies)
Tall glass or vase
Water

Optional:
Other items to test
Measuring Tape or Rulers

Set up takes about 2 minutes. Draw a rainbow in a paper.

Then move the glass in front of the rainbow from one side to the other.

Did you see that? Boom… it flipped. The red is on the right and the purple is on the left. SO COOL, right? Did your kids say WOAH… do it again? Good!

It really is that simple. This is a basic demonstration of light refraction (bending of the light) and reflection.
