Glow in the Dark Slime: Perfect for Sleepovers

Sleepovers become very exciting for both the children and their parents. It is a time when friends come together; great memories are always made.

What if you were to do something different on those special nights? How about glow-in-the-dark slime to bring some magic to a party?

Why Glow in the Dark Slime is Perfect for Sleepovers

Sleepovers are always accompanied by laughter, late-night whispers, and perhaps some games.

Glow-in-the-dark slime works well with this environment and changes a regular sleepover into a glowing expedition. This kind of slime is suitable for group activities, so children will have more opportunities to engage with one another while designing numerous slimes with lots of surprises.

Believe it or not, the glow-in-the-dark slime is also very soothing. An example is its smooth and soft texture that will help you take away some tension through your bedtime activities.

When the lights are off, the glowing designs act as warm night lights, which make the dark not so scary.

The Science Behind Glow in the Dark Slime

Why does slime glow in the dark? What’s the science behind it?

Actually, the secret to glow-in-the-dark slime lies in phosphorescence and some interesting chemistry.

Understanding Phosphorescence

Phosphorescence is an aspect of photoluminescence. The material absorbs the light when light falls onto it. After we remove the light source, it glows. 

The reason slime glows at night is due to the combined effect of light and phosphorescence. 

Another aspect of photoluminescence is fluorescence, but it is light-dependent since after we remove the light source, the fluorescent material will no longer emit light. It still glows, even if there isn’t a light to fuel the phosphorescence; this makes the slime able to keep shining through the night.

Explaining the Chemical Reactions

Its phosphorescent compounds will absorb photons when under light. These substances bear a special kind of atomic structure that allows the storing of energy for some time. 

The more phosphorescent material in the slime, the brighter and longer-lasting its glow in the dark will be. 

In addition to phosphorescence, invisible chemical reactions occur when we make glow-in-the-dark slime. A cross-linking reaction would be mixing school glue and borax. This is where the whole is greater than the sum of its parts. 

The organic macromolecules within these polymers bind to one another, forming a much greater cross-linking network. Slime is so malleable and we can mold it into several shapes because it’s made out of this enormous cross-linking solid network.

How to Make Glow in the Dark Slime Step-by-Step

Making glow-in-the-dark slime is a great family activity that you can do with the kids. This step-by-step guide will walk you through the process.

2 Ingredient Glow in the Dark Slime

To make glow-in-the-dark slime, you usually only need 2 ingredients, namely glue and phosphorescent powder.

Ingredients:

1. Clear or white glue (1 cup): the base of the slime.
2. Phosphorescent powder (1 tablespoon): the key to glowing.

Of course, you will need a little activator, such as borax solution or liquid starch.

Instructions:

First, the glue is tipped into a big bowl. Then, sprinkle the phosphorescent powder into the adhesive and mix it well to make the powder even. 

Next, add the activator to the mixture slowly. The stirring process is continued until slime starts pulling off from the sides of the container. We can get it out of the bowl and begin to knead after the mixture thickens. 

This way, you can always add more drops of the activator solution and continue to knead. Do this until the slime becomes a soft, non-sticky mixture. 

Go ahead and shut off the lights in the room to test the glow in the dark. Put it under a light, if necessary.

Optional Add-ins for Extra Fun

Make your slime more fun by adding some extra ingredients.

• Glitter: Make your slime sparkle.
• Food coloring: Add a few drops of neon food coloring to enhance the glow.
• Essential oils: Make your slime smooth. Lavender or peppermint essential oils can give your slime a nice scent.
• Miniature toys or beads: Add these little gadgets to your slime for a more tactile experience. They can make stretching and squeezing your slime more fun.

Optional additions: glitter, food coloring, essential oils, miniature toys, or beads

Instructions:

1. Pour the glue into a mixing bowl.
2. Add the phosphorescent powder and stir until well mixed.
3. If needed, add water to make the slime more elastic.
4. Gradually add the slime activator while stirring constantly.
5. Once the mixture starts forming a ball and pulls away from the sides of the bowl. Take it out and knead it with your hands until you reach the desired consistency.
6. Add glitter, small toys, food coloring, and essential oils during the kneading process.

Follow these steps to make amazing glow-in-the-dark slime.

Green Glow in the Dark Slime

Have you ever wondered why the color of glow-in-the-dark slime products usually glows green? Let’s dive a bit into color science. The first and foremost reason is that green phosphor has the best luminous effect and stability.

Stability

When absorbing the light energy, the green phosphor can efficiently convert it into visible light; environmental factors like humidity, temperature changes, and the like do not make it susceptible. So, green glow-in-the-dark slime will have a longer glowing duration than other colors.

Eye-friendly

The human eye is most sensitive to green light. In the visible spectrum, a wavelength of about 520-570 nanometers accounts for green light and is at the peak of eye sensitivity, which means any green light of the same energy is brighter than others. 

Compared to blue or red night lights, green lights are softer and more comfortable; they do not easily cause eye fatigue. Therefore, the reason green appeared in glow-in-the-dark slime most commonly is that.

Low cost

Lastly, producing green phosphors is a relatively mature process with relatively low costs. So, green glow-in-the-dark slime is more popular and affordable in the market.

Cleanup Tips After the Fun

Glow-in-the-dark slime is fun, but no one, especially moms, wants a mess to be found all over the house. Here are some simple clean-up and storage tips for a much-cleaned-up play area.

Easy Ways to Clean Up Slime

By and large, slime doesn’t stick to hands or furniture. Unfortunately, carpets or clothes love it. If children drop it on the carpet, you must clean it.

First up, we’ll gather any big pieces of slime. Next, come the smaller, stickier leftovers; we try a few of these hacks on them.

1. Vinegar solution: The vinegar breaks down the stickiness of the slime; hence wiping it off using a damp cloth is very easy.
2. Freezing: Put an ice pack on the slime and leave it for 10-15 minutes. Scrape off the hardened slime using a butter knife or credit card gently. Use rubbing alcohol or dish soap for treatment of any residue.
3. Tape tip: Place tape on top of the slime and then peel it off; the slime should stick to the tape.

Storing Leftover Slime for Future Play

Proper storage of the glow-in-the-dark slime will keep you having fun for a long time. Here are some tips to keep your slime in top condition:

• Airtight Container: Get a Ziplock bag or an acrylic box with a lid. Storing slime in an airtight container will help it not dry out.
• Cool, dry place: Ideally, a cool, dry place would be best—like inside a drawer or on a shelf. Keep it out of direct sunlight because heat and humidity can worsen your slime.
• Label and date: Date the container to know which batch must be used first.
• Check regularly: It will help you to recognize problems, such as mold or odors, and get spoiled slime out of your house quickly.

Liam, 10, says of his sleepover:

“Me and my friends had the greatest time! We made a ton of glow-in-the-dark slime and used it to make monsters and creatures that glowed. It’s so neat seeing it glow from all over! We stayed up all night with ghost stories and our new slime creations. It was the best sleepover ever!”
