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

好吧，还记雀斑是如何在纹身墨水微胶囊内使用紫外线敏感染料吗？

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

那么，如果我们将有材料放入这些微胶囊中并用它们制成纹身墨水呢？

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，大约与发一样宽， 充满带负电白色颜料和带正电黑色颜料。

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，你也可以将热敏染料放入微胶囊中，你可以制作不同纹身墨水，这些墨水会在不同温度下改变颜色。

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?

所以我想，我们为什么不取一些微胶囊，在其中装入对紫外线敏感变色染料，然后用它制作纹身墨水呢？
