Want cake? Help me with tute questions. Apparenty, the cake is a lie so you won't get any anyway. You can still help me :D There *might* be cake, you never know!
Oh yeah, talk about the video... So anyway, this is a hydraulic jump created in a small tank during a Water Engineering practical in The University of Adelaide. In this video, the downstream gate was lowered, and what you can observe is the position and strength of the jump changing. The jump moves downstream, and becomes weaker.
I can't be bothered going into detail at the moment about what's happening, but I think you get the jist. The water jumps around like crazy and energy is dispersed. Hooray for it.
