ughh! i hatee this problem too! but i found a clever way to make them all a bright greenish color when you take them inot a dark room. (: ok first what youll needis a container and then you fill it all up with cold water and put ice in it too. then you take the silly bandz and put them into the container. then afterwards you have to put them in your fridge for twenty minutes or in your freezer for fifteen either way it works evenly. so then when you take out the container with the water, ice, and silly bandz, and you put it under a light for ten to fifteen seconds and go into a dark rooom and then theyll glow a bright greenish color!! by the way, yes even if you have the container with the sillybandz in the dark fridge it will still have the same affect.
