You see a flow of simulated water (silicon oil) down a low angle channel. You can use a magnet to place shapes into the liquid flow, and to turn the shapes to see how the streamlining or turbulence of the flow around them is affected by their position and orientation.
As you turn the shapes you can see that the orientation can affect the flow of water past the ship. If the shape is pointing into the flow, the water passes smoothly. If the shape is across the flow there is turbulence at its edges.
Streamlining is the shaping of an object, like the hull of a ship, to reduce the amount of resistance to its motion through the water. A curved shape allows the hull to move smoothly through the water. Streamlining reduces the amount of water resistance to the movement of the ship, and conserves energy.
