The Beer Song :)
A fish slingshot for helping our finned friends get over dams is now being tested in the wild:
"Originally designed for fruit, Whooshh turned its technology into a tool to help safely send fish over dams blocking the course on the Columbia river in Washington state. Under tests right now with the Department of Energy and the Washington Department of Fish and Wildlife, the Whooshh tubes could be shooting more fish over dams in the near future. A test this past summer showed that fish will voluntarily enter the tube. When they swim into the entrance, the vacuum sucks them in and gives them initial boost; after that, elevated pressure behind the fish keeps them moving at about 15 to 22 miles per hour till they go flying out the other end."
