Filmed by The School of Physics & Astronomy at the University of Edinburgh, this is the FloWave Ocean Simulator, a 2.4 million liter (634,013 gallon) controllable research pool for testing devices and prototypes in wave and tidal current conditions. Inside the 5 meter (16.4 foot) deep tank, 168 absorbing wave makers line the walls, reliably simulating all kinds of water oscillations.
Watch the FloWave single and four spout tricks above. So fun!
