Glittery Juice!!!

When I look at a bottle of J2O Glitterberry, I can hear my fathers voice from the past saying, "what's the point of that then." Or maybe I'm getting to a certain age where, looking at the bottle of juice with glitter in it just mystifies me and gets me to thinking what is the point of putting glitter in a bottle to drink. It adds no flavour! What's the point of that then...
