Why there are rainbows experiment?
Each of these colors bends at a different angle because each color travels at a different speed inside water or glass. When you reflect the light back out of the water using the mirror, you’re reflecting the white light that has been broken up (from refraction) into the full rainbow of colors, and a rainbow appears!
How do you make a rainbow out of glass?
Fill the glass almost to the top with water. If you are using sunlight, place the glass so that it is half on and half off the edge of a table, and so that the sun shines directly through the water, onto a sheet of white paper on the floor. Adjust the paper and the glass until a rainbow forms on the paper.
How do rainbows work?

How does a rainbow work?
When sunlight hits a rain droplet, some of the light is reflected. The electromagnetic spectrum is made of light with many different wavelengths, and each is reflected at a different angle. Thus, spectrum is separated, producing a rainbow.

Carnival glass has been known by many other names in the past: aurora glass, dope glass, rainbow glass, taffeta glass, and disparagingly as ‘poor man’s Tiffany’. Its current name was adopted by collectors in the 1950s from the fact that it was sometimes given as prizes at carnivals, fetes, and fairgrounds.
