@physedreview I did it for a couple of years at my old school. Amazon's black lights are great. Don't waste your time with glow in the dark gaffer tape, if possible spray painting bowling pins work the best for visibility. Strobe lights and fog machine take it over the top.
@CoachGore_PE I just purchased these myself and going to have kids practice the next few weeks. Any recommendations on number of balls per group, shoes or no shoes or any other tips. Thanks!
@GingerAaron During a competitive game, 3rd graders on different teams were able to talk out their problem when they saw cheating. I put them together, and they worked it out. All the work we put in to problem solve small issues is working.
