Mortar & Pestle

 Idea 1 : Games

My idea is that in the century of 52nd, this is the new sensation of sports that is called pesmopool. In order to win this game the player have to shoot only one ball into the hole.

Idea 2 : Exercise

The pestle is the dumbbell and the mortar is the incentive of  doing a sit up so that the muscle will build up more fast.

Idea 3 : Business 

The situation here is that they are trading each other with one's item. The guy on the right is trading his pestle to the guy on the left. It's kind like the barter system.
