so ive been looking online and found some uv reactant pool balls most of them are on the more expensive side but i think this would be easier than trying to make my own, also maybe these would be easier to detect?....

also just searching google images for glow in the dark pool gave me new inspiration to this project so for sure im not going to sleep tonight trying to figure out a way to incorporate more lights and make them do some coos stuff
