How to Make Glow in the Dark Bubbles – A Fun Science Activity for Kids and Adults

Making glow-in-the-dark bubbles is more than just a fun DIY—it’s a fantastic hands-on science activity that fascinates both kids and adults. Whether you’re planning an evening backyard party, a themed celebration, or simply want to make a magical playtime moment, these glowing bubbles are a hit. They’re easy to make at home with a few simple ingredients and no special equipment.

Ingredients

Here’s everything you’ll need to create your own glowing bubble solution:

• 1 cup water
• 1 tablespoon clear dish soap
• 1/2 teaspoon glow-in-the-dark pigment powder

These ingredients are affordable and safe for kids to use with supervision.

Instructions

Mix the Glow Base

Start by combining the clear dish soap and the glow-in-the-dark pigment powder in a small bowl. Stir thoroughly until the mixture is evenly blended. This forms the glowing base of your bubble mix.

Add Water

Slowly pour in the water and gently stir to combine everything. Avoid stirring too hard to prevent foaming.

Charge the Glow

Once mixed, place your bubble solution in direct sunlight for at least 2–3 hours. This charging step is crucial, as the glow pigment needs light exposure to become fully activated.

Bubble Time

After charging, use a straw or bubble wand to start blowing bubbles in a dark room or outside just after sunset. You’ll immediately see the magical effect as the bubbles glow while floating through the air.

Benefits of This Craft

Making glow-in-the-dark bubbles isn’t just entertaining—it’s educational and sensory too. Here are some of the key benefits:

• Encourages STEM learning: Kids get to explore how light interacts with pigment and observe cause and effect in action.
• Inspires creativity: You can use different shaped bubble wands, containers, or even experiment with other pigments.
• Affordable and reusable: Most of the ingredients can be reused for future DIY projects.
• Great for sensory play: The glowing effect adds a visual component that enhances tactile and motion-based activities.

Tips for Best Results

To make your glowing bubbles as impressive as possible, follow these practical tips:

• Charge well: The longer the bubble mix is exposed to sunlight, the brighter the glow.
• Use in the right lighting: Dusk or a dark room is ideal. The glow fades quickly in bright light.
• No black light required: The glow pigment is charged with sunlight and doesn’t need UV light.
• Use clear dish soap: Colored soap can reduce visibility of the glow.
• Store in clear container: This allows light to reach all parts of the mix evenly.

What Does It Look Like?

When used properly, the bubbles have a faint but magical glow, especially visible when they catch the light just after dusk. The glow is usually green or blue, depending on the pigment you use. It adds a surreal, otherworldly effect to your backyard or play area and looks amazing in slow-motion videos or photographs.

How to Store

To keep your glow-in-the-dark bubble mix for another day, follow these steps:

• Use a sealed container: Airtight jars or bottles prevent the solution from evaporating.
• Recharge before use: If stored, the glow pigment will need to be recharged again under sunlight before reuse.
• Avoid contamination: Don’t dip dirty wands or straws into the container. Pour out a small amount instead.

Proper storage can make the mix last for several weeks, although the glow may weaken over time.

Glow-in-the-dark bubbles are a simple, safe, and captivating activity for all ages. They combine science, art, and fun in a way that leaves a lasting impression—perfect for summer evenings, backyard playdates, or science-themed parties. With just water, dish soap, and glow pigment, you can create your own magical experience right at home.

FAQ

Can I use glow sticks instead of pigment powder?
No, glow sticks contain chemicals that are not safe for skin contact or blowing into bubbles. Always use non-toxic glow-in-the-dark pigment powder.

Where can I buy glow pigment powder?
You can find glow pigments online or at most craft stores. Look for non-toxic, child-safe labels.

Do these bubbles stain?
If you use a high-quality glow pigment and clear dish soap, staining is unlikely. However, avoid contact with fabric and always test first.

Why don’t my bubbles glow well?
Make sure your mixture was fully exposed to direct sunlight. The pigment needs time to charge. Also ensure you are in a dark enough space to see the effect.

Can this be used indoors?
Yes, but you need a very dimly lit room to see the bubbles glow properly.
