I use a funnel to blow the table tennis. Why is the table tennis sucked in the funnel?

In the gas, the pressure is low where the velocity is high
1. When the air is blown down from the funnel, the gas velocity at the lower end of the funnel is large and the pressure is small. Under the action of atmospheric pressure, the table tennis ball is pressed up
2. When the air is forced upward from the funnel, the gas velocity at the lower end of the funnel is small, the pressure is high, and the air pressure is greater than the atmospheric pressure, so the table tennis ball is pressed down
