So yesterday, I think I made my own PSI Ball. When I made it, I didn't know what to do with it. I kinda just, let it go, then went on my marry way. So what are the uses of a PSI ball? And what does it mean if you "shell" it? How would I do that? Also, can you see your own PSI ball? When I made mine, my eyes were closed. I feel like if I opened my eyes, then it would go away. Thanks!
