把一乒乓球压入盛有水：

您好！我可以用英文回答您的问题吗？如果您想要中文回答，也请告诉我。

Regarding your question, if you are asking what happens when a ping pong ball is submerged in water, then the answer is that the ball will float on the surface of the water. This is because the density of the ball is less than the density of water, so it is buoyant and will not sink.

If you have any further questions or if there is anything else I can help you with, please let me know!
