This would be from the 70's and 80's maybe earlier. My sister had a ring toss and I had fishing. About 6" wide, 8" tall, and 1" thick. You filled it with water and pushed the button to make it work. When you pushed the button air would shoot into the water making the rings float a round and you hope they would land on the spikes. Anyone remember these, know the name, and if they are still available?
