We could make all sorts of things out of spider silk, like bridge cables, bulletproof vests, airplanes, and biodegradable bottles.

我们可以用蜘蛛丝做各种各样的东西，比如桥缆、防弹背心、飞机、可降解的瓶子等等。

So there are plenty of hurdles left to overcome before we can even make enough spider silk for a steady supply of hats, let alone turn it into bulletproof vests and bridge cables.

所以，在制造出足够供帽子生产的蛛丝之前，我们还有很多障碍要克服，更不用说用蛛丝做成防弹背心和桥缆了。
