In a room, there is a large fan on the floor pointing upwards. Marcellus is standing to the side of the fan, and Tabitha is standing directly above it, with her loose, lightweight skirt. What happens to Tabitha's skirt when the fan is turned on, and why doesn't Marcellus feel the wind from the fan? Provide a very brief response.
When the fan is turned on, the air it pushes moves upwards along the direction the fan is pointing. Since Tabitha is standing directly above the fan, the air current flowing upwards catches her lightweight skirt, causing it to billow upwards around her. Marcellus, standing to the side of the fan, does not feel the wind from the fan because the primary column of air is moving vertically, and he is positioned outside of its upward trajectory. The air around him remains relatively still compared to the air being directly pushed by the fan.
