Here's a few ideas!
- Fill a glass 2/3 full. I found that tall glasses worked better. Grab a white piece of paper and head outside or next to a sunny window. Tilt the glass so the sun shines through the glass onto the paper. Keep experimenting with angles until you achieve a rainbow!
- If it is a warm sunny day, head outside and get the garden hose out. Spray a misty stream. You may need to adjust angle or position to get the rainbow to show up.
- Use a crystal or a prism. Hold up to light to refract (bend) the light into it's separate colors. You can find prisms at local craft stores or on Amazon (here or here).
- Look in the parking lots. Cars sometimes leak oil or other fluids (don't touch!). You can often see a rainbow in the puddle, especially in the sunlight.
- Blow bubbles! If the sun hits the bubble right, you can see a rainbow in it!
To help remember the order of the rainbows colors, just remember the rainbow's friend ROY G. BIV:
