The Akihi prism is made of premium K9 crystal polished glass, 6 inches (150 mm) in length and 1.17 inches (30mm) in side length.

It is maybe a good tool for you. Use it to spark your creativity to take the unique photo, it will be a cool thing in your life.

Still don't know how to use it to create rainbow?
1,To show the rainbow, you need to prepare flashlight or simple led light of smart phone, a black piece of paper and our prism.
2,Create a small slit in black paper and let the led light through this slit which will form a ray of light.
3,The prism will refract the white light and create a rainbow on a target away from the prism.
Note:If move the target, you will find the rainbow are bigger and more distinct. The rainbow is clearer in the dark place.

Not only to create rainbow, it's also a perfect tool for science experiments teaching light spectrum physics.
