I'm putting all of my jars together and making labels today and have wondered about the same things. (That's why I decided to rummage through this thread for extra ideas).This may not be the right place for this post, but I have a quick question about GID liquid. I know that highlighters soaked in water will glow. Also some laundry detergents and tonic water. My question is about the laundry detergent. Do you just mix it with water and it will glow, or do you have to use it full strength? Also as for the tonic water does it glow for a long time, or does is die down after a while. Do any of these things have an effect on the ingredients in your jars? I guess that was 3 questions too. I know these might be silly questions but I just don't know the answer to them, and I am willing to bet one of you will.
