2. Glow Stick Balloons
Fill balloons (white or colored) with glow sticks for an awesome party decoration, or just as a fun past time for the kids. After your balloons are half filled with air, carefully insert a glow stick or two, and then finish blowing them up and tying them off. These would be cool hung upside down from the ceiling!
3. Glow In The Dark Bowling
Water bottles and glow sticks make for perfect glow-in-th-dark backyard bowling pins. Make at least six of these, and use any kind of ball (basketball, soccer ball, etc.) to knock down your glowing pins.
4. Glow Jars
Although these only last a few hours (you can reactivate by breaking up another glow stick), their magical feel makes them well worth it. The kids have a lot fun watching them glow in the dark!
