Fruity Rainbow Bombs + Science of Rainbows

Fruity Rainbow Bombs 7

Well, I’m still doing my best to use up the box of Fruity Pebbles from my End of The Rainbow Cereal Treats and Fruitfetti Pebbles White Chocolate Cookies. This weekend I’ll be crashing on the couch with my sister, Casey, and her boyfriend, Don. I threw together these quick 5-ingredient no bakes to thank them for letting me stay at their place. Toss some Fruity Pebbles, Nerds, fruit bites and melted white chocolate in a bowl and you can easily have some for yourself!

I think I’ve done history lessons on all of these ingredients! Instead, in honor of my science studying sister and sort of in-law, I’m going to do a science lesson. Oooo… science… About rainbows. Oooo… rainbows… Who’s excited?

A rainbow is a meteorological, related to the atmosphere, phenomenon that is caused by the reflection, refraction and dispersion of light in water droplets, rain, mist, dew or even spray from a waterfall or hose. This process of ‘splitting’ light results in a spectrum of light in  the shape of an arch appearing in the sky. Remember, our perception of color is dependent upon light. The most common sequence of color is Newton’s sevenfold, red, orange, yellow, green, blue, indigo and violet.


Rainbows most be viewed from 42 degrees from the opposite direction of the light source. Even if an observer sees another person standing right ‘below’ the rainbow, the other person will not be able to see the same rainbow.

In rare cases, rainbows may take unexpected forms. Rainbows can be circular or have double arcs. They may even occur in moonlight but they will be white and are known as fogbows or moonbows. ‘Upside down’ rainbows have been seen on winter days, due to the interplay between light and ice crystals. Extremely rare, is the monochrome or red rainbow which may happen at sunrise or sunset.

And now… back to the food.

    • The Fruity Pebbles are actually a cereal and they are the main ingredient in this fruity, rainbow recipe. You could sub Rice Krispie treats for a less fruity version. To keep the rainbow look, I’d add a couple tablespoons of rainbow sprinkles.
      The candy (Nerds and Welch’s snacks) could be switched out for equal amounts of any similar candy. Skittles or jellybeans would also be yummy here.
      This is a very forgiving and easily customizable recipe because there is no baking involved.
