What You’ll Need
Here’s all you need to make this fun experiment a success:
- Clear cups or glasses
- Water
- Food coloring (various colors)
- Oil (vegetable or canola works best)
- Baking soda
- Vinegar
- A dropper or small spoon for careful pouring
You can easily swap regular food coloring for gel food coloring for richer colors if you have it on hand.

Directions to Follow
- Fill your cups: Start by filling each cup or glass about halfway with water.
- Add colors: Use the dropper or spoon to add a few drops of food coloring to the water. Make sure to use different colors in each glass to create a vibrant display!
- Prepare the oil: On top of the colored water, gently pour a layer of oil. The oil will float above the water, creating a separation that highlights how differing densities work.
- Create the fireworks: In a small bowl, mix a tablespoon of baking soda with a cup of vinegar. As you pour this mixture carefully into your colored water, you’ll see the fizzing action that mimics the “fireworks” bursting beneath the surface.
- Observe the magic: Watch closely as the colors and bubbles dance! Encourage your kids to watch for how long the colors stay suspended in the oil.
Best Ways to Enjoy It
To enhance the fun, consider hosting a “Science Fair Day” where your kids can present their fireworks creations to family or friends. Pair this activity with themed snacks like popcorn or fruit skewers to create an all-day event filled with learning and laughter.
How to Store
Once you’re done with the experiment, there’s no need for leftovers! However, if you have extra colored water, you can store it in the refrigerator for a day or two. Just remember that the fizzing effect won’t last, so it’s best to enjoy it fresh!
Helpful Cooking Tips
- For smoother pouring, consider using a funnel when adding oil to your cups.
- Encourage kids to make predictions before starting. Ask them which colors they think will mix well and which will float.
- Use clear containers so the effects of density and buoyancy are more visible.
Recipe Variations
Feel free to play around with this fun experiment! Try using different oils like coconut or olive oil for varied results or experiment with adding glitter to the water for a sparkly effect. You can also switch up the food coloring to create holiday or seasonal themes for extra excitement.
