Product Description

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 activities 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.

How big is the black light?

The black light is the perfect size to fit on your key-chain. In case you want to take your creation with you wherever you go, your black light will be your trusty companion.
