We cracked the secret to making your favorite concoctions glow in the dark! Glow Powder is a fine powder called zinc sulfide that glows an eerie green light when the lights go off. Our team of creative teachers packed the included activity guide with a bunch of great ideas... from glowing alien blobs to glow-in-the-dark putty. When the lights go off, most people think that it's time to go to bed. The after dark scientist knows that when it's dark, everything comes alive with an eerie glow! Try using our Glow Powder for your own activites and ideas. It's perfect for a new twist on Halloween Jack-o-Lanterns and other glow in the dark crafts.
Adult supervision is required with all chemicals.

What Does It Teach?
Learning about the science of things that glows requires an understanding of two important terms - fluorescence and phosphorescence. It's also important to note that not all zinc sulfide glows, but luminous zinc sulfide does glow!
Fluorescence - This type of luminescence occurs when some form of radiation, such as light, causes an object to glow. For example, fluorescent papers and poster boards glow in the daylight. They may seem to glow even brighter under black light (ultraviolet), but in either case, as soon as the light is removed, the glow stops. Fluorescent things do not glow in the dark all by themselves – they require some other form of energy such as ultraviolet light to “excite” them.
Phosphorescence - Phosphorescence is just like fluorescence, except that the glow continues even after the light used to excite it is removed. “Glow in the dark” toys phosphoresce brightly in total darkness after being “charged” or excited by ordinary white or ultraviolet light. Glow Powder works by absorbing surrounding light energy and then releases that energy when the lights go out. It's called a phosphorescent It's the perfect way to get your students excited about energy... and a great way to celebrate Halloween! Just add glow powder to almost any of our favorite products and you'll have an eerie new take on your favorite experiments!
So, how does zinc sulfide work? Imagine that an atom looks something like our solar system. The sun would be the nucleus consisting of positive charges called protons and neutral charges called neutrons. The planets spinning around the sun would be similar to the electrons of an atom in orbits around the nucleus.
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. It’s as if Earth were to move farther away from the sun into the orbit of Mars or Jupiter.
The electrons will remain in the excited state as long as they receive light to energize them. But, when the light used as an exciter is removed, the electrons will slowly return to their original lower orbits. As they do so, they give up the energy that excited them in the form of light.

I used the glow powder to make glow in the dark putty for a class room halloween party. The kids loved it and it worked well. (Posted on 5/31/13)

We used Steve Spangler's glow powder to make glow in the dark slime with 200 elementary aged students. They loved it!! We even set up a black light room so they could check out the glowing! Thanks for all the great products and ideas that get kids excited about science! (Posted on 5/31/13)
- Happy Glowing Review by Rage

I bought the glow powder for myself just because I like glow-in-the-dark stuff. I could have gotten more powder for the same price from another website, but the included mini blacklight makes it worth it. The jar was full of glowing polka dots within seconds of my package arriving. :D !

The glow doesn't last as long as traditional glowing products because this is pure chemistry. Eventually I will mix the powder with some clear paint and put it on something, but for now I'm still enjoying simply using the jar of powder as a night light. - Glo powder Review by Denise Goodman

- A glowing hit! Review by Kim Walker

The Louisiana Children's Discovery Center had a great time at our "Super Science After Hours" event and this glow powder was awesome. The kids favorite was making the glow in the dark puddy/goo to paint with! So fun! (Posted on 5/31/13)
- Best stuff ever! Review by Lizb

I finally bought a few jars of this powder for my science lab and the children (ages 4-8) have used this powder in so many different ways. We put it in clear slime, Elmer's glue gak, jelly crystals, test tube lava lamps, clear spheres, and we even made glow in the dark messages on black paper. This product does glow in the dark on its own without a black light but the addition of the black light makes it much brighter. I will continue to reorder! (Posted on 5/31/13)
- Great value Review by Pam

I bought two of these Glow-in-the dark powders to add to our worm goo, jelly crystals, and bouncing balls. We could have only bought one jar. It goes a long way. We had plenty in one jar for all of are experiments. We had a Halloween party and had 15 kids ages from 3 to 11 and 10 teens ages 12 to 18 They each made a bouncing ball with glow powder in them, and not all of the kids were careful with their measurements. We also added glow powder to our jelly crystals for rainbow tubes that glow, and in our worm goo. Great fun. Great quality, Super glow. (Posted on 5/31/13)
- Love this Review by Marilou

This powder is so versatile. I just wish it came in a bigger size! We have had tons of fun with the powder, but the simplest thing we've done is a test tube filled with water and a little glow powder. Charged quickly in a black light, it glows brightly for a long time. (Posted on 5/31/13)
- The hit at the Annual TechFest in Dayton Review by Hilmar Koerner
-
TechFest is a free event about sharing and learning about math, science, engineering, and technology in the Dayton/Miami Valley region. The Dayton Section of the American Chemical Society was there with a hands on demonstration - making glow in the dark slime. We ordered a bunch of the kits to make the slime from PVA and Borax. This was a hit and the children (of all ages) loved it. We had over 2000 kids pass our table and make glow in the dark slime that they were able to take home.
thank you
