Neccessity is the mother of invention, as they say, and she has created some fairly unusual children. Animal Tracking - Satellites let scientists follow elephants, whales, and manatees. Baby Stretcher - When an infant is injured, this child-size stretcher provides more protection. Biodegradable Golf Tee - Take your swing, then leave the tee where it stands. Nature will do the rest. Boomerang - From aboriginal weapon to child's toy, learn about the forces that bring boomerangs back. Velcro - The idea for this handy fastener came from a walk in a field thick with burrs. Inventors and Inventions II: Explore some of the discoveries that opened the heavens to humanity. Leonardo da Vinci - Artist and inventor Leonardo da Vinci created - on paper, at least - the first helicopter. Galileo's Telescope - This Renaissance man risked all to discover the secrets of the spheres with his telescope. The Wright Brothers - On a North Carolina beach, Orville and Wilbur Wright took flight and made history. Lowell's Observatory - In his Arizona observatory, Percival Lowell looked to Mars for signs of life.
