These lights look cool and weird at the same time so you know I HAVE to try it. I am going to hang it from a tree so its either going to look spooky, like the pod people are coming, or look like a giant glow in the dark snot. Either way when I do try it I will post it.
The link for this longer longer exists so I can not give credit for this picture or idea to anyone.
All you need to do is put a water balloon with a glow stick on the inside in a stocking and hang from trees or ceiling. I'm starting to think of a orange glow in the dark stick won't look make it look like snot.
