A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky.
It takes the form of a multi-colored arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun. Rainbows can be full circles; however, the average observer sees only an arc formed by illuminated droplets above the ground, and centered on a line from the sun to the observer’s eye.
And they are so magnificent, people are inspired to base so many things on them. Like cakes!
Of course, that was just a scientific explanation on what rainbows are. We aren’t here to host a physics lesson, we’re here to show you how to make something cool.
And here’s how to make something cool that involves rainbows: A rainbow mandala buttercream cake!
It looks really fun, and it’s pretty easy to make. Check out the recipe below:
