While it’s not possible to control “real, outdoors rainbows”, you can create artificial rainbows indoors using various methods. One way is to use a prism, which can split light into its component colors and create a rainbow effect. Another way is to use a special diffraction foil, which is a material that can split light into its component colors, just like a prism. In both cases, you’ll still need the magic ingredient to make it happen : real sunlight.

A prism is a transparent object that can split light into different colors, like a mini rainbow! It’s usually shaped like a triangle, made of glass or plastic, and works by bending or refracting light as it passes through. The different colors of light have different wavelengths, so they’re bent at different angles, causing them to separate into a rainbow-like pattern.

Sir Isaac Newton was the one who figured out all this cool stuff about prisms. His experiments led to the development of the modern understanding of color and the spectrum of light. Today, prisms are still used in scientific research and technology, as well as in art and design. You can find prisms in all sorts of things, like cameras, microscopes, and even jewelry! They’re also used in science experiments and in decoration, like the rainbow crystal.

Prisms themselves are not typically dangerous, but they can create a fire hazard under certain circumstances. When sunlight passes through a prism, it can create a focused beam of light that is very intense and can potentially start a fire if it is directed at a flammable material, such as paper or fabric. This is known as the “burning glass effect.” However, this is generally not a major concern if prisms are used safely and correctly. It’s important to position the prism carefully and avoid directing the beam of light toward any flammable materials.

The Rainbow Sticker is the alternative to prisms and rainbow crystals.

Made of a special diffraction foil, it’s designed to split light into its component colors. Diffraction is a phenomenon that occurs when light waves encounter an obstacle or a slit that is comparable in size to the wavelength of the light. When this happens, the light waves bend and spread out, creating interference patterns that can be seen as colorful bands. When sunlight hits the sticker, it passes through the diffraction foil, which causes the light waves to diffract and spread out into a rainbow pattern. The diffraction foil in the Rainbow Maker Sticker is carefully designed to split light into the colors of the rainbow, just like a prism. As the light waves pass through the foil, they are refracted, or bent, at different angles, depending on their wavelength. This causes the different colors of the rainbow to spread out and create the characteristic rainbow pattern.
