Fizzy Rainbow Science
A fizzy science experiment and a cool way to teach kids about the colors of the rainbow.
Equipment
- Arm & Hammer Baking Soda, 16 oz (3 Pack)
- Sakura 15262 18-Piece Koi Assorted Water Color Tube Set
- Pinnacle Mercantile Plastic Squeeze Condiment Bottles with Red Tip Cap 16-Ounce Set of 6 Wide Mouth
Ingredients
- 3 cups baking soda
- 6 colors of tube watercolor paint red, orange, yellow, green, blue, purple
- 6 oz water
- 1-2 cups vinegar
- Squirt bottle medicine droppers, or spoons
- a large tray or cookie sheet
- Flour sack towel or paper towel
Instructions
- Blend watercolor paint and water then add the mixture to 1/2 cup of baking soda until the color is smooth.
- Repeat the first step for each of the watercolor paint.
- Make an ark by laying globs of red onto the sheet. This will be the top of your rainbow so make sure you have enough space for the rest of the colors.
- Continue laying the remaining colors but line them up before touching the colors to each other.
- Dry excess liquid by laying a paper towel on top of your rainbow. You can do this the night before the experiment for a drier and fizzier result.
- Watch the rainbow fizz as you pour some vinegar over it using a dropper, squirt bottle, or a spoon.
