我们构建了一个模型的旋转虫洞由剪切和粘贴两个克尔时空。其结果是，我们得到了一个旋转的薄壳虫孔与奇异物质在喉部。两个候选人的外来物质被认为是：（i）一个完美的流体;（ii）各向异性流体。我们表明，一个完美的流体是无法支持一个旋转的薄将虫洞。相反，具有负能量密度的各向异性流体可以是这样的几何形状的源。
We construct a model of a rotating wormhole made by cutting and pasting two Kerr spacetimes. As a result, we obtain a rotating thin-shell wormhole with exotic matter at the throat. Two candidates for the exotic matter are considered: (i) a perfect fluid; (ii) an anisotropic fluid. We show that a perfect fluid is unable to support a rotating thin-shall wormhole. On the contrary, the anisotropic fluid with the negative energy density can be a source for such a geometry.
