A water balloon with a glow stick on the inside, in a stocking, hung from trees, patio cover, or the ceiling. Same pin elsewhere said: "Put a glow ball in a white stocking and hang many from trees or the ceiling." But what are glow balls?
My mom used to make these! DIY Easter Egg Garland wrap a balloon with string, roll it around in the liquid starch. After you have soaked the balloon put the balloon on a cup and let it dry overnight. Pop the balloon and you have your egg
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!
