Halloween Candy Science Experiments

Halloween Candy Science Experiments from Standard Deviants Accelerate

Halloween has come and gone. Like many of you, we have more candy than we should ever eat! So why not use some of it for some science experiment fun? Not only can you eat some of the candy but you can learn some cool things too! It is a win win in my homeschool book!

Halloween Candy Science Experiments

Acidic or Not?

The word “acid” comes from “acidus,” the Latin word for sour or tart.

If something’s acidic, it will produce carbon dioxide bubbles when combined with baking soda. Carbon dioxide is the same gas you breathe out when you exhale.

Is sour candy acidic? Let’s find out!

Supplies:

  • Bowl
  • Measuring cup
  • Water
  • Fruit-flavored or sour candy (Pixy Stix, LemonHeads, Nerds, WARHEADS)
  • Spoon
  • Baking soda

Directions:

  1. Dissolve the candy in a half-cup of water. (Pixy Stix will dissolve easily. Other candies will take longer. If the candy can be easily crushed, try that to make it dissolve more quickly.)
  2. Sprinkle a spoonful of baking soda into the candy-water mixture.
  3. Watch for bubbles.
  4. If you see bubbles, the candy is acidic.

Candy Rainbow
Candy makers turn candy into a rainbow of colors using dyes. Just like when you’re mixing paints , it’s takes a combination of dyes to create certain colors. Colors get mixed up. Did you know you can separate them again?

In this experiment, water and coffee filter paper will separate a drop of candy dye back into different colors. Brown candies work well. Why? Because they use a variety of colors together to make brown dye.

Supplies:

  • A white paper coffee filter
  • Dyed candy such as M&Ms, Skittles, or Reese’s Pieces (brown pieces work well)
  • A glass filled with a half-inch of water

What to do:

  1. Place a drop of water on a plate.
  2. Place a candy piece on the water and let color dissolve.
  3. Cut a rectangle out of the coffee filter. Use the flat part, not the sides.
  4. Fold the coffee filter paper rectangle vertically (long-ways). This will help it stand up in the glass of water.
  5. Measure up about an inch from the bottom and dab a drop of candy-colored water onto the paper.
  6. Fill a narrow glass with a half-inch of water.
  7. Place the filter paper rectangle in the glass of water so that the water line is below the colored drop of candy dye.
  8. Watch the water move up to the top edge of the paper.
  9. Check the paper at 15 minutes, 30 minutes, and 1 hour. You should see the different colors emerge on the filter.
