Instructions: First, put some water in five small cups.

Then, add some different food dye to each cup.

After that, take the baking soda and add a small amount to each cup.

Finally, watch the colours explode everywhere!

1 WE need a cup of vinegar and a cup of baking soda and color

2 We put the color in the cup of baking soda then put the vinegar in it

Here’s how it works:

🌈 What You'll Need:

• M&M's (or Skittles also work)

• A white plate

• Warm water

🧪 Steps:

1. Arrange M&M’s in a circle or pattern on the plate (around the edge works well).

2. Slowly pour warm water into the center of the plate—just enough to touch the bottom of the candies.

3. Wait and watch—within a few seconds, you'll see colorful streaks spreading from the M&M’s toward the center, forming a rainbow-like pattern.

🧬 Science Behind It:

• The candy coating on M&M’s is made of sugar and food coloring.

• When water touches the coating, it dissolves, releasing both sugar and dye.

• The dyes don’t mix immediately due to something called water stratification (a mix of temperature, density, and surface tension).

• This creates sharp boundaries between the colors, forming the rainbow effect.

🧠 Why It’s Cool:

• Shows diffusion (movement of particles from high to low concentration).

• Demonstrates how different colors have different weights and densities, affecting how they spread.

• It’s safe, quick, and fun—perfect for kids or a classroom!

1. We drop one drop of color in each cup.

2. We need to put one spoon baking soda in each cup.

3. Finaly pour the water in each cup. So you can see the color exploding.

Materials: baking soda, food dye.

Instructions: First, put some water in five small cups.

Then, add some different food dye to each cup.

After that, take the baking soda and add a small amount to each cup.

Finally, watch the colours explode everywhere!

Materials Needed:

• Baking soda (sodium bicarbonate)

• Vinegar (acetic acid)

• Dish soap (optional, for foamy eruption)

• Red food coloring (optional, for lava effect)

• A container (like a plastic bottle or cup)

• Modeling clay or paper mache (to shape the volcano)

• Tray or large plate (to catch the mess)

Steps:

1. Build the volcano structure

   • Place the container in the center of the tray.

   • Use modeling clay or paper mache to shape a volcano around the container, leaving the top open.

2. Add the ingredients

   • Put 2–3 tablespoons of baking soda into the container.

   • Add a few drops of dish soap and red food coloring (optional).

3. Prepare for eruption

   • Slowly pour vinegar into the container.

4. Watch the eruption!

   • The mixture will bubble and overflow, simulating a volcanic eruption.

5. Clean up

• Dispose of the mixture and clean the tray and materials.
