Concept of Mixer

The main point in working of mixer is: it is not necessarily the sharpness of blade that cuts, but, it is the sharpness combined with the speed of rotation that cuts something that is put in the mixer jar.

Well, I keep saying - 'It is not about the sharpness but about the speed', whenever the mixer is turned on and A comes running to observe it.

As your child keeps growing, you could get better in explaining the complete concept.
