All it takes is a few easily-obtained materials to turn a bottle of Mountain Dew into a glow in the dark bottle of Mountain Dew. You can't drink it, but that doesn't detract from the fun of making the bottle glow.
Once made, they can be saved each year and then a new glow stick can be added inside. The kids love flying these around the yard at night! Glow-Bug Craft-Could be a fun camping craft. Hanging these in the trees for a camp out party would be awesome!
