Rainbow In A Jar

Take a large glass jar, fill it 3/4 with water. Drop a single drop of food coloring into the jar from about a foot above the jar, so the coloring makes it's way almost to the bottom. Try different colors.

Spinning Colors

Cut a circle out of heavy paper. Divide the disk into 6 equal sections. Color each section a different color of the rainbow. Poke the circle onto the point of a sharpened pencil. Show the circle to the children. Ask them to predict what they will see when you spin the circle. When the circle is spun, instead of seeing 6 colors, you will see white ( or close to white, depending on the purity of the colors and how equal the sections are). This is the reverse of what happens when a raibow is made from white light separated into the six colors seen. This experiment take those 6 colors and whirls them together to make white.

Rainbow Magic

Things needed:
Whole milk
Food coloring
Clear bowl or pie plate,
Dawn dishwashing liquid (blue)

Pour the milk in the bottom of the dish enough to cover the bottom. Add a few drops of food coloring randomly. Put a drop of Dawn on each color or on the side of the dish near each color. Watch! Although you cannot see it, milk contains fat that do not mix with the watery food coloring. Whenever the dishwashing liquid touches the milk, it breaks up the fat which then spreads out. This allows the food color and milk to mix. It will continue on for quite a while. The children can leave and come back and it still will be in motion. Be sure that you use blue Dawn dish detergent. The children will find this amazing & some children will watch for a long time.

Making Rainbows

Place a small mirror in a glass of water and tilt it against the side of the glass. Then stand the glass in direct sunlight so that the mirror reflects a rainbow on a wall. Name the rainbow colors with the children (red, orange, yellow, green, blue and purple.). Explain that sunlight contains all these colors mixed together, but when it hits the water (or raindrops in the sky) all the colors are separated.
