Will it Blend? Not unless it utilizes several Physics concepts.
The actual pitcher of the blender works as a cavitation chamber. Cavitation is the rapid formation and collapse of air cavities in a fluid. Such cavities are formed by rapid changes in pressure, which is where the blade comes into play. In addition to breaking down food into smaller chunks, the blade also rapidly bombards the mixture with small air bubbles that, when they pop, cause shock waves to further break up the food.
This concept is not exclusive to blenders. Mantis shrimps use a variant form of inertial cavitation to propel themselves in the water. For many devices, such as boat propellers, cavitation is undesirable. This ‘accidental’ cavitation usually causes an increase in noise, vibrations, and significant damage to the propeller itself.
