Oi / Ingredient grinder

Oi
Oi

'Oi' is a calorie-saving grinder devised to improve the conditions of Africans suffering from starvation. Due to the lack of their food supply, their staple food usually takes a form of porridge, which consists of powder and water. To turn ingredients into a form of powder, people usually use mortar which takes a huge amount of effort and calories.

Considering their insufficient conditions, even the slightest calories should matter.
With 'Oi', changing the interaction of grinding from crushing to spinning, unnecessary calorie consumption can be saved. After all, saving is earning!
