Ingredients You’ll Need

The beauty of Glowing Fireworks in a Jar is how it comes together with everyday ingredients, each playing a unique role in creating the sparkling effect. You likely have everything you need on hand, and every element is essential for achieving those mesmerizing, floating colors.

Clear glass jar or mason jar: A transparent container lets you watch the colorful magic unfold from every angle.
Warm water (to fill the jar ¾ full): Warm water helps the food coloring disperse quickly and dramatically.
2–3 tablespoons vegetable oil: The oil separates from the water and holds the food coloring droplets, setting the stage for the burst effect.
Several drops of liquid food coloring (assorted colors): Choose your favorite shades for a rainbow display; the more variety, the better the fireworks!
1 fork or small whisk: This helps break the food coloring into tiny droplets, ensuring a spectacular show when added to the jar.

How to Make Glowing Fireworks in a Jar

Step 1: Prep the Jar

Start by filling your clear glass jar or mason jar about three-quarters full with warm water. Set it aside on a flat surface where everyone can easily see the action. The warm water is key—it encourages the food coloring to spread out in beautiful, feathery streaks.

Step 2: Mix the Oil and Food Coloring

In a small bowl, combine 2–3 tablespoons of vegetable oil with 4–6 drops of different food coloring. Don’t worry about being exact—just aim for a fun mix of colors. The oil prevents the food coloring from mixing with the water right away, building anticipation for the main event.

Step 3: Break Up the Color Drops

Use a fork or small whisk to gently stir the oil and food coloring mixture. Your goal is to break the food coloring into small droplets suspended in the oil, but avoid over-mixing. This only takes a few seconds! You’ll see tiny beads of color floating in the oil, ready for their grand entrance.

Step 4: Create Your Glowing Fireworks in a Jar

Quickly pour the oil and food coloring mixture into the jar of warm water. Watch closely as the food coloring droplets sink and begin to burst, releasing stunning trails of color that swirl and dance through the water—just like real fireworks! This is the magical moment when Glowing Fireworks in a Jar truly comes to life.

Step 5: Explore and Enjoy

Take a few moments to observe the shapes, colors, and patterns as they develop and change. If you want an extra wow factor, try shining a blacklight on the jar with tonic water instead of plain water. The colors might shift, but the glowing effect is absolutely mesmerizing for nighttime fun!

How to Serve Glowing Fireworks in a Jar

Garnishes

While you won’t be eating this craft, you can absolutely dress up your Glowing Fireworks in a Jar! Tie a bright ribbon around the jar’s neck, add a festive tag, or pop in a sparkly straw for extra flair—especially if you’re using it as a table centerpiece or party decoration.

Side Dishes

Pair this activity with a platter of colorful snacks like fruit skewers, rainbow popcorn, or fun drinks. Kids and guests will love having something to munch on while they watch the fireworks show unfold in the jar. It’s a great way to turn craft time into a full-blown celebration.

Creative Ways to Present

Set up a “science lab” station with multiple jars and let everyone create their own Glowing Fireworks in a Jar using different color combinations. For parties, use mini mason jars so each child can take home their own magical creation. Or, add LED tealights underneath the jars for a glowing effect at night—so enchanting!

Make Ahead and Storage

Storing Leftovers

If you want to keep your Glowing Fireworks in a Jar on display, simply cover the jar loosely with a lid or plastic wrap. The colors will eventually blend together, but you’ll still get a pretty tie-dye effect for a day or two. Just keep it out of direct sunlight to preserve the vibrancy as long as possible.

Freezing

Freezing isn’t recommended for this activity, as the oil and food coloring won’t freeze in a way that preserves the fireworks effect. If you want to experiment, try using ice cubes made with tonic water for a frosty twist—just be ready for a totally different science adventure!

Reheating

Since Glowing Fireworks in a Jar is a no-cook, room-temperature craft, reheating isn’t needed. If the water cools and you’d like to try the project again, simply start fresh with new warm water and repeat the steps. A fresh jar always delivers the best wow factor!

FAQs

Can I use any type Craft, Kids Activity

Vegetable oil works best because it’s light in color and allows the food coloring to show up vividly. Other oils like canola or sunflower also work, but avoid olive oil, as it can have a strong smell and color that might interfere with the effect.

Why does the food coloring form bursts in the water?

This is a fun science moment! Food coloring is water-based, so it doesn’t mix with oil. When you pour the mixture into the jar, the food coloring droplets sink through the oil and then burst into the water, creating the firework streaks you see.

How can I make a glow-in-the-dark version?

To make Glowing Fireworks in a Jar truly glow, swap the regular water for tonic water and shine a blacklight on the jar. The quinine in tonic water glows under UV light, making the whole display shimmer and pop—perfect for nighttime fun!

Is it safe for kids to try this activity?

Absolutely! This project is safe, non-toxic, and a wonderful hands-on experiment for kids of all ages. Just remind little ones not to drink the mixture and always supervise younger children, especially when handling glass jars.

Can I reuse the jar for another round of fireworks?

Yes, simply rinse out the jar and start over with fresh warm water. The only limit is your supply of food coloring and oil! This makes Glowing Fireworks in a Jar a repeatable, endlessly fun activity for rainy afternoons or parties.
