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.

我們每個人都遇到過這樣的難題：怎麼才能擠出瓶子裡剩下的最後一小團番茄醬？麻省理工學院（MIT）的一組研究人員開發出瞭一種巧妙的新技術。該容器已經過特殊的設計改造，能夠讓番茄醬等任何粘稠的液體輕而易舉地從瓶子裡流出來。科學傢們在瓶壁的內側塗抹一層粗糙的表面，並在上方覆蓋一層輕薄的物質，然後鋪上一種能夠註滿溝槽並形成非常順滑表面的液體。這個塗層的過程能大量減少浪費的情況。

The Ice Maiden team is heading out across a frozen Norwegian lake at the start of its final training exercise. In September, these soldiers will begin their historic journey hoping they’ll succeed and inspire a generation of women. Home for the next few weeks and for the 80 days of the expedition will be a small tent. It will be the bedroom, living room and kitchen.
