I made this glow in the dark "night light" for Mya's summer camp. They are super easy to make, all you need are:
1. A glass jar
2. Glow-in-the-dark paint and/or Dimensional Paint Writer
3. Glow-in-the-dark stickers
#1 #2 #3
To activate, expose paint to UV light source, such as outdoor or flash light. Perfect camp activity for Girl Scouts too =)
