The round, one-person tables have an air-filled tube around them and wheels at the bottom.

这个单人面围了一根充气管，底装了轮子。

It's made of air filled tubes and machines that change its shape by moving its corners.

它是由充气管和通过移动角改变形状的机器组成。

But how can this silly inflatable tube save your life?

I think they ought to apply it to those inflatable dancing tube characters you see outside car dealerships, because they're already full of hot air.

我认为他们应该将其应用于在汽车经销店看到的那些充气式跳舞管角色，因为他们本身就充满了空气。
