Here is a tip to make your own Rainbow.
Fill a glass of water (almost to the top) and place it at the very edge of the counter in a dark kitchen. Place a sheet of plain white paper on the floor a few inches away from the counter. Put two pieces of masking tape over the front of a flashlight so that the light comes out of a slit about 1/8 inch (0.3 cm) wide. Shine this light across and down into the water as shown in the figure. When a narrow beam of light is passed through a glass of water, a spectrum can be seen on a white sheet of paper.
Can you see a small rainbow on the white paper? If not, move the flashlight around a little until you achieve the best results.
Now that you know what to look for, you will begin to notice small rainbows wherever sunlight falls on water, glass, or plastic that has a tapered shape. Look for rainbows produced by the beveled edge of a mirror or a chandelier.

great advice on how to make a rainbow
Ever heared of FengShui crystals …
They are polished crystals with many faces
Hang them up at your windows where you have sun and your house will be filled with rainbowspots ….
You can also make mobiles like that to hang up and the spots will be moving …

ohhh… really cuz im going to try this for my science project my teacher is makeing us do this. so yeah i need this to work. 😛
Awesome just did it for my 2 and 4 yr olds and worked like a charm. You need opaque tape so that it blocks almost all the light with the exception of the thin slit you leave open. The rainbow can be seen on light colored rug and your skin!
