This is the 3 types of ways that i used mortar and pestle as something else

So the 1st one will be COMMUNICATION where the it can be a morse code system where the  mortar as the base and the pestle as the clicking tool to create the different speed of the sound to represent those words.

2nd will be the FURNITURE where it can be build as a sofa where the mortar as the seats and the pestle as the  handle on the sofa.

The 3rd one will be a punishment tool where the children can be punished to hold the  mortar and the pestle the head but NOT ON THE HEAD.
