It is spring, which means rainy days and
if we are lucky: rainbows!
Rainbow Volcano
Materials:
Baking Soda (about 1.5 cups)
7 small cups (I use Dixie cups for easy clean up)
Food coloring or Koolaid mix (red, orange, yellow, green, blue, indigo, and violet)
Gallon of vinegar
A place to make a giant (but fun) mess
Directions:
Fill each cup about 1/4 to 1/3 full with baking soda
Squeeze one to two drops of food coloring in each cup
Arrange cups like a rainbow (red, orange, yellow, green, blue, indigo, and violet)
Quickly pour vinegar over all cups and watch it foam
Repeat until you are out of supplies!
Rainbow Fizzies
Materials:
Food coloring (red, yellow, blue)
Baking soda (about 1/2 cup)
Vinegar (1/2 cup)
Droppers or spoons
Clear dish
Directions:
Cover the bottom of a clear dish with a layer of baking soda
Drop food coloring in three sections (about 4 drops of each color)
Use droppers or spoons to drop vinegar over color spots
Repeat until colors blend and create each color of the rainbow
Rainbow Skittles
Materials:
Package of Skittles
Warm water
Clear dish
Directions:
Place Skittles around the edge of the dish in rainbow order (there is not a blue/indigo in the original Skittles package. You may want to purchase the tropical package if you would like to be a little more accurate).
Pour warm water in the center of the dish - at first only 1 cup of water.
Watch as the colors begin to disperse in the water
Pour additional warm water until the Skittles are completely submerged.
Watch as the colors continue to spread and then see if you can find a floating "s" from the Skittles.
Rainbow Shaving Cream
Materials:
Shaving cream (foam not gel)
Red, yellow, and blue food coloring
Plastic wrap
Masking tape
Directions:
Cover your work area with plastic wrap and tape it down using the masking tape
Place three blobs of shaving cream on the plastic wrap
Using the food coloring squeeze 1 - 2 drops of coloring on each shaving cream pile (red, yellow, and blue - separately)
Place shaving cream on top of the food color droplets
Have your children mix the colors until the have created a rainbow
Note: Using gel food coloring is best.
