All you need is a glow stick, a small container a paintbrush, and paper
Step 2: For the Glow
Crack the glow stick and empty it into the container
Step 3: Do It
Take the paintbrush and draw!
Step 4: Glow!
Shut the lights off and have fun.
Note: chemicals in the glow sticks can be harmful with contact to eyes and can cause aggravation to sensitive eyes or noses
