The invention is directed to a fishing bobber includes an upper float portion and a lower float portion. The upper float portion includes an outer surface terminating at one end in a first opening of a first diameter and terminating at a second end in a second opening of a second, larger diameter and having a tube extending from the first opening in the direction of the second opening. The lower float portion includes an outer surface terminating at one end in a first opening of a first diameter and terminating at a second end in a second opening of a second, larger diameter and having a tube extending from the first opening in the direction of the second opening. Mating the second opening of the upper float portion to the second opening of the lower float portion causes the tube of the upper float portion to mate with the tube of the lower float portion to form a channel passing through the combined first and second portions and a joint formed between the upper float portion and the lower float portion and between the tubes results in a cavity. The bobber may be formed using ultrasonic welding.
