Making Our Own Glow Stick
Kids absolutely love glow sticks and today we are going to be making a glow stick at home! This article contains multiple ways of making glow sticks including some glow stick kits you can purchase because since we originally wrote this article in 2011 some of the supplies available have changed.
Making a Glow Stick with Zinc Sulfide Powder
My kids LOVE glow sticks. We must keep the glow stick companies in business because I always have to have a stock of glow sticks on hand.
They love to crack them and take them to bed with him! My son, Nicholas’ dream is to get his hands on an unopened box of 15 glow sticks and crack them all at once.
So we couldn’t pass up this simple experiment to let him make his own glow stick when we found it in a kit.

Supplies Needed to Make Glow Stick
We got all of this in a kit but (at the time) there are lots of sites on the internet that have directions for making your own glow sticks as well as where to locate the zinc sulfide powder (which seems to have changed in the last 10 years).
Directions to Make a Glow Stick
Nicholas loves doing science experiments because he gets to wear his safety gloves. However, these are obviously adult size gloves and they can’t be very safe if they inhibit him from grasping items well.
Daddy held the test tube while Nicholas measured the zinc sulfide and transferred it to the test tube.
Add the water and vegetable oil.
Place top on the test tube and shake to combine the ingredients.
We made GLOW!!
Zinc Sulfide Powder and Glowing Experiments for Kids
I have searched the internet for this glow stick kit or information on what the measurements would be if you bought these ingredients independently of a kit. There is not a lot of information out there! Here are a few of the more helpful resources I found in that search…
Glow Powder Makes Glow Sticks Glow
Zinc Sulfide powder is called glow powder in this cute fireflies in a jar experiment from Steve Spangler and they use just a little bit in combination with glue to create glowing “fireflies” in a jar. There is a great explanation of phosphorescence in this experiment and how zinc sulfide works:
When the electrons in the atoms of special molecules like zinc sulfide become excited, they move farther away from the nucleus — into higher or more distant orbits. In order to become excited, the electrons must take on energy. In this case, light provided the required energy to cause the electrons to move to a higher energy level.Steve Spangler Science
Zinc Sulfide Powder Makes Slime Glow
Another resource I came across when researching this homemade glow stick experiment was that the Montgomery Schools MD site has steps for creating slime in the classroom that glows using zinc sulfide. You can find the directions here. They recommend:
Stir in the glow agent into the glue gel of PVA solution. You want 1/8 teaspoon of zinc sulfide powder per 30 ml (2 tablespoons) of solution.Montgomery Schools MD
Substituting Glow in the Dark Paint for Zinc Sulfide Powder
Many of the suggestions for making glow in the dark projects with kids were to use glow in the dark paints that are available everywhere now instead of zinc sulfide powder. We have done that many times here at Kids Activities Blog because it is easy and includes the coloring as well! Here are a few of our favorite glow in the dark paint ideas:

Glow Stick Kits for Kids
Since we couldn’t find the original glow stick kit used above in this article, we went out and found some others that might be fun to play with at home and then created a glow stick with one of them…keep reading! It appears that one of the things that has changed in the last 10+ years is that it is hard to find a single experiment kit. Most of the kits have a whole bunch of glow in the dark science experiments for kids.
Best Glow in the Dark Science Kits for Kids
- Glow-in-the-Dark Science Lab from Thames & Kosmos – this is the one we purchased (see the additional information about making homemade glow sticks at home below). This has 5 glow in the dark experiments for kids including making your own glow sticks. The kit is created to help kids learn about phosphorescence and includes a UV flashlight to observe some of the experiments.
- Glow in the Dark Lab from National Geographic – make your own slime, grow your own crystal, make putty light up and marvel at a flourescent wernerite rock specimen. There is a glow in the dark guide to explain why everything is so glowy!
- Big Bag of Glow in the Dark Science – This has a whole bunch of STEM fun science projects…over 50 of them! Kids will make invisible ink, glowing putty, jelly balls, crystals, fluffy rainbow slime, monster blood, glow dough, magnetic mud and more.
- Scientific Explorer Glow in the Dark Fun Lab from ALEX Toys – 5 awesome glowing activities including making glow in the dark slime and a human powered light bulb. There is also a diy glow stick kit inside.
Making a Glow Stick with Fluorescent Pigment
We bought the Glow in the Dark Science Lab from Thames & Kosmos because one of the experiments was clearly making homemade glow sticks. It was a simple process with good results.
The kit came with some folding test tube stands that we recommend using tape to secure and everything needed to complete this homemade glow stick activity for kids.
Supplies Needed to Make a Glow Stick with Fluorescent Pigment
- Yellow fluorescent pigment
- Pink flourescent pigment
- UV flashlight
Directions to Make Glow STick with Fluorescent Pigment
Fill 2 test tubes with 10 ml water each.
Using a teeny tiny spatula, put a tiny amount of the fluorescent pigment in each test tube – yellow in one and pink in the other.
Tip: When they mean tiny, they mean tiny…if you use too much, it won’t glow properly!
Add the tops to the test tubes and shake well.
Darken the room and make both liquids glow in the dark by shining the UV flashlight on them.
Make a Glow Stick with Mountain Dew Soda?
OK, one thing that I kept running across in my how to make a glow stick research was the rumor that people could make glow sticks by adding baking soda to a bottle of Mountain Dew pop. There are even gorgeous glowing pictures on the internet saying it was made with Mountain Dew and baking soda.
So, if you happen to have heard and seen such information, here is one of the best videos I found that answer the question, can you really make a glow stick from Mountain Dew…
Can You Make a Glow Stick from Mountain Dew Video
OK, so maybe we won’t be trying that one at home.
But…there was one thing that I think next time I want to try – making a solar powered reusable glow stick.

How did you make a glow stick? Do you have a favorite glow in the dark science kit for kids?
I love this! So cool. I can’t believe it glows that well. I think it will have better results then the incredible growing frogs sitting on my kitchen counter right now.
You guys always do the NEATEST projects! When I was a kid the most exciting it got was when it rained and I could play with my Barbie’s outside in the puddles, pretending they were lakes! Nicholas is so lucky to have a creative and adventurous mom like you!
Don’t underestimate playing in puddles for developing awesome kids
the project looks interesting!! where did you obtain the kit from?
My daughter is doing a glow stick science project and yours looks very fun and simple. Where did you obtain the zinc sulfide powder kit you have displayed?
The kit came from Constructive Playthings. They have a store in Plano at Parker and Independence and a website http://www.constructiveplaythings.com. Sign up for their email list because they usually send out $5 off coupons with a $25 purchase. Have fun!
My daughter would be enthralled! This is going on our must-do list!
You can make it without harsh chemicals, and possibly cheaper by using a bottle of mountain dew, a dash of baking soda and about 3 cap fulls of hydrogen peroxide. It will glow the same color yellowish green. Also, it may deter people from ever wanting to drink mountain dew again!
I’m totally two years too late on this, but amazon stocks xs vinyl gloves! http://www.amazon.com/Tillotson-Multicare-Vinyl-Gloves-Extra/dp/B005NHBTO6
How much zinc sulphide do you use at a time?
What are the measurements for each component if we wanted to make this in test tubes? It sounds like an awesome activity and I would love to use for our VBS but I need to know how much to get and how much for each kid to do this experiment.

Elaine…OMG! You are so right. You have stumbled across a post that was written in 2011 and hasn’t been updated since that time. I have added it to our schedule to update with all the measurement information. Unfortunately, that will likely be too late for your event. I apologize for that.
