If the 1-Ball is more dense and it's the same size as the rest of the balls then it will have more mass, and therefore, weigh more.......... lol, I'm gullible, I'm going to have to check that out haha
Diamond smart tables have a density sensor in the cue ball separator that reads the density of the balls, when the cue ball passes through it, because it has a higher density reading, it gets kicked off and returned as a cue ball....well, that same density sensor will kick off the one ball as well, so it has to be turned down until it lets the one ball pass by, yet still kick off the cue ball
