Clean, clear jar with lid
Thin glow stick
Table covering or tray
With a grown-up's help, cut the tip off the glow stick.
Place the open end of the glow stick in the jar and shake it back and forth so that it splatters. Turn the jar as you splatter.
Add a small pinch of glitter, sprinkling onto the sides of the jar where the splatters are.
Cover with lid and take into a very dark room.
Fireflies are not flies but beetles and do exist in Colorado! They hang out by permanent water sources like ponds, lakes, and streams. Watch this project at: https://youtu.be/LRNWJVQRFYw
