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!
For camping or late nights at the beach - Leave of Mountain dew in bottle (just don't drink it all), add a tiny bit of baking soda and 3 caps of peroxide. Put the lid on and shake - homemade glow stick (bottle) solution. Now I don't want to drink mt dew
Here is a sure fire way to WOW this Summer! Make your own glow in the dark chalk using only two ingredients plus water. This chalk glows in the dark, under UV light, and it even works in broad daylight! (SUPER Summer FUN from Growing a Jeweled Rose)
