These floaters have been made with increased levels of water soluble ingredients.
This means that when they are in the water they ooze off their smell, colour and flavour into the water.
This leaks off into the surrounding area enticing the carp to feed. You can actually see the Oozing Floaters pumping their ingredients out into the water.
There is a multitude of ways to use them, they can either simply be hair rigged, tied on using a lasso, attached using a bait band or glued to the shank of a hook.
