Introducing the PoolFish! I designed the PoolFish to be a wallet-sized companion for learning how to align shots in billiards for 2.25" balls. Essentially, if you slide the tail of the fish centered up underneath the object ball, you can align the fish with where you need to hit the cue ball to make the correct point of impact. For slice shots that don't involve a rail, this can help the beginner player visualize where the cueball needs to go to provide the correct impact. If you like, you can put a little chalk mark in the center of the cue ball area, and shoot for the chalk. I might redesign these for 1.75" balls in the future, or put alignment lines on the top.
