Well, remember how the solar freckles used a UV-sensitive dye inside of the microcapsules of the tattoo ink?

好吧，还记得日光雀斑是如何在纹身墨水的微胶囊内使用紫外线敏感染的吗？

So what if we put interesting materials inside of these microcapsules and made tattoo inks with them?

那么，如果有的入这些微胶囊中并用它制成纹身墨水呢？

Each sheet contains millions of microcapsules, about as wide as a human hair, filled with negatively-charged white pigments and positively-charged black pigments.

每张纸包含数百万个微胶囊，大约与人的头发一样宽， 充满带负电的白色颜和带正电的黑色颜。

Well, you could also put heat-sensitive dyes inside of microcapsules and you could make different tattoo inks that change color at different temperatures.

好吧，你也可以热敏染入微胶囊中，你可以制作不同的纹身墨水，这些墨水会在不同的温度下改变颜色。

So I thought, why don't we take some microcapsules, load it up with a UV-sensitive, color-changing dye, and make a tattoo ink out of that?

所以想，为什么不取一些微胶囊，在其中装入对紫外线敏感的变色染，然后用它制作纹身墨水呢？
