I've went swimming on acid many times. We had a pool in our backyard back in my fry days and swimming on acid usually happend every "FRY"day in the summer. I remember 2 things trippin me out alot about frying balls in the water. Swimming down and looking up at the surface from underneith and having my eyes at about water level and watching the waves come. I didn't really feel it was very dangerous at the time. I always rememberd to come up for air.
