Not bounce in the sense that a ball bounces- they were designed for use over water, where they 'skipped' across the surface just as happens when you skim a stone across a pond. The speed and motion in which they were travelling meant that they were able to use the surface tension of the water as a kind of springboard, moving too fast for their weight to make them sink.
