I have been using floats now for over 45 years and always need one that was not on the market. These are all hand made from balsa and have split shot in them. The first three from L to R are weighted with different number of split shot to give them weight for casting. The last two on the right are sinkers. With this type of float you can get it to sink at a very slow rate and use them for count down floats and by adding more weight in the balsa you can make them sink faster. If you want to try something different you can paint them and add eyes and hook. I do not know how many times I have had fish hit the float. To make these get a stick of 1/2" square balsa stock and split it down the middle, next hollow out the center of each half big enough to hold the shot. Next take a piece of spinner wire and crimp on the split shot and clamp the two halves together. Balsa is soft and will form itself to the wire. I use thin CA and glue it together and then cover the entire float in CA. It is now solid and waterproof. Shape with sandpaper. Shape it first then cover it with thin CA. With practice you can make them do what you want.
