Scientists have already used this technique to make a plastic coating that basically acts like self-healing paint.

科学家们已经应用这项技术制造塑料涂层，像自我修复漆。

The first time I did this, I wondered if the tacks were being pulled together by static attraction on the plastic coating or something.

当我第一次这样做时，我想知道大头钉是否会被塑料涂层或其它东西的静态引力拉到一起。
