“floats Linx Bubble 1 1/4″””

The standard round fishing bobber has an internal spring and a top and bottom J-shaped wire to provide pinch points to hold the bobber at a certain depth

In general, the traditional round plastic fishing bobber requires more force to pull under and can hold heavier bait. They have two different colored halves to help detect subtle bites where the bobber may just roll over. Other signs of bite detection may include a twitch, disappearing quickly, steady movement, or if drifting in a stream or river, a halt.
