If I had a pool I would totally try this out. Put a glow stick in a balloon for pool lanterns. Pool party on a Summer night! I think this could work pinned up on the fence of a backyard without a pool, too, so really great idea for any outdoor BBQ/party!
Light Up the Dark ~ Fun party idea. Cut open a glowstick and shake it into an empty bottle. Whirl and swirl it around for fun glow in the dark colors. You can also add some water or oil to the jar to give it bigger and a more even color.
