Can you understand from the movement of the snake - if the air is moving upwards or downwards?

उत्तर
Yes, we can understand from the movement of the snake whether the air is moving upwards or downwards. If the paper snake moves in a clockwise direction then we can say that the air is moving upwards.
If the paper snake moves in an anticlockwise direction then we can say that the air is moving downwards.
