P1 says to P2 : “what nice air there is today”. P2 doesn’t believe there is air. He tires to convince P1 that there is no air. First he asks if he can see it, P1 tries and cant really see it. Then he asks if he can grab it, P1 tries but can’t grasp it. Then he asks if he can taste it, P1 tries but can’t taste anything. …. And so on the funnier u acts it out the better. In the end P2 tells “you cant see it, u cant taste it, u cant grab it……, there is no air!!!” there are two possibilities to end the drama even P1 one gets convinced by that and leaves or P1 in the end holds his hand over the nose and the mouth of P2, who after a while falls to the ground and confesses that there is air anyway.
