The glass is quite interesting, but I don't think the photo really does justice to the radioactive green ambiance. The bottle worked quite well too, except that I was surprised to see a very visible beam inside the bottle. Then I realised that I'd just opened the bottle to pour the glass, and it was full of a mixture of water vapor and CO2, which showed the beam beautifully.
Some time soon I really do need to set up the big camera on a tripod and do this properly, rather than trying to hand-hold it without flash.
