Machine that can shape water Answered
The National Maritime Research Institute of Japan has a machine that can create shapes in the water such as hearts and stars. That's just the small one. The larger machine can make much bigger collisions between waves. There's some research around safety here to merit such a large setup, but I'm just happy with the splashes and the over-the-top reactions of the reporters. Always fun to see them shout "sugoi!" and "waaaaaaa!" over and over.
