Use this glow-in-the-dark phosphorescent powder by mixing it with a medium to illuminate everything in your life. Great for making glow-in-the-dark art, teaching how germs propagate, and more.


Step 1: Mix
Mix glow powder with a medium (try nail polish, acrylic paints, slime, soap, etc.) Use a ratio of 2 parts medium to 1 part powder. You may want to increase this ratio for the brightest glow and use a clear or pale medium. When applying, use a white base for the best effect.

Step 2: Charge
Charge the powder by leaving it in the sunlight or under a UV lamp.

Step 3: Glow
Put it in the dark and enjoy the glow!

What happens?
The phosphors in the powder absorb energy from UV light and then release this energy as light.

What is phosphorescence?
This type of luminescence occurs when some form of radiation, such as light causes an object to glow. The glow continues even after the light used to excite it is removed.
