KidHaven Press, 2006 - 32 עמודים
Humans have always dreamed of breathing underwater as fish do. Now, an Israeli engineer has moved that dream one step closer to reality. Alan Bodner designed an underwater breathing device that imitates fish gills and extracts dissolved, breathable air from water. The marvel of gills is explored, along with the story of Bodner's invention and the first use of his revolutionary system in 2006.
