One of my team members (hi Analese!) has been raving about these diving gems for literal years and I finally bought two packs of them for our Idaho trip And she was right! My kids spent HOURS making up games with them - I was shocked how much they loved them!  (Analese warned me not to bother with the bigger packs of smaller gems because they’re much less fun and they get lost easily) LTKKids LTKSwim
