        It's something we've all struggled with – how to get that last drop of ketchup out of the bottle. Here at MIT they've developed this clever new technology. The container has been specially engineered to enable the ketchup or any other sticky liquid to slip out easily. Scientists coat the inside with a rough surface. They then put a thin layer over it and they cover that with a liquid which fills in the troughs and forms a very slippery surface. This coating process could cut huge amounts of waste.
       
        我们每个人都遇到过这样的难题：怎么才能挤出瓶子里剩下的最后一小团番茄酱？麻省理工学院（MIT）的一组研究人员开发出了一种巧妙的新技术。该容器已经过特殊的设计改造，能够让番茄酱等任何粘稠的液体轻而易举地从瓶子里流出来。科学家们在瓶壁的内侧涂抹一层粗糙的表面，并在上方覆盖一层轻薄的物质，然后铺上一种能够注满沟槽并形成非常顺滑表面的液体。这个涂层的过程能大量减少浪费的情况。
