Many people rely on a cup of coffee or two to wake them up in the morning or pick them up during the working day, but now a chemist has come up with a speedy alternative to crafting a cuppa. 很多人喜欢在早晨起床后或工作间隙喝一两杯咖啡帮助提神，但如今，一位化学家发明出了能代替烘焙咖啡的快速提神制剂。 U.S. biochemist Ben Yu has created 'Sprayable Energy,' which claims to be the world's first caffeine - based topical energy spray. 美国生物化学家本·宇制造了“能量喷雾剂”，据说是全世界第一支以咖啡因为主要原料的局部能量喷雾剂。 He said flagging workers can spray a 'shot' of caffeine onto their skin without experiencing a strong buzz, loading up on unnecessary calories or being stuck with a nasty aftertaste like they might get from drinking energy drinks or coffee. 这位化学家说，工作疲惫的人可以直接用它在皮肤上“来一发”咖啡因，无需受到咖啡机嗡嗡声的折磨，不用担心摄入过多卡路里，也不会在喝完咖啡或其他能量饮料后嘴里出现难闻的味道。 |
