It's an extreme measure to save water - a shower curtain that physically¹ ejects the user after four minutes.

节水出绝招啦——洗澡时间超过四分钟，浴帘就会把洗澡的人“赶”走。

Specifically targeted at those who spend leisurely² periods of time in the bathroom, London-based artist, Elisabeth Buecher, created the unique product to force people to change their water-wasting habits.

这是专门针对那些在浴室里优哉游哉的人而发明的，伦敦艺术家伊丽莎白•比彻发明了这个独特的产品，迫使人们改变浪费用水的习惯。

Named 'Spiky³', the shower curtain features soft plastic spikes⁴ which lie flaccid during the shower, and upon reaching the time limit, dramatically inflate⁵ and jut⁶ outwards⁷, forcing the user out.

这款浴帘名叫“尖尖穗”，其特色在于柔软的塑料刺，它在人们沐浴时会松松垮垮地垂下，一旦达到时限，就会骤然充气向外伸出，把人推出浴室。

'Spiky' functions by rigging the tap with a sensor⁸ which triggers the non-painful spikes after reaching the four-minute limit.

“尖尖穗”的工作原理是利用传感器控制水龙头，在超过4分钟时限后，它就会触发“尖尖穗”，且不会让人感到疼痛。

The colorful soft spikes are attached to a plastic shower curtain, and after expanding with air, trap the bewildered user, ensuring the shower swiftly becomes an uncomfortable and cramped⁹ experience.

彩色的柔软“尖尖穗”是固定在塑料浴帘上的，它在充气膨胀后会卡住人，让人不知所措，随即淋浴会变的不舒服、受拘束。

In the humorous demonstration¹⁰ images, a woman is seen having a shower in a stall, with the spikes hanging loosely on the wall. She is seen to be engaging in some in-shower singing, wasting water while taking her leisurely wash.

搞笑的示范画面里，有个女子在浴室里洗澡，“尖尖穗”在墙上低垂着。只见她哼着歌，懒洋洋地洗着澡，很浪费水。

The soft spikes are next seen to inflate and immediately jut into the terrified user, who clutches on frantically¹¹. She tries to reclaim¹² her balance, and is unable to continue her enjoyable experience, as the spikes take up all available space.

接下来，柔软的“尖尖穗”开始膨胀，瞬间伸向这个惊愕失色的女子，她慌忙乱抓，试图保持平衡，但无法继续那快乐的体验，因为“尖尖穗”已经挤满了所有空间。

Although undoubtedly¹³ an ingenious water-saving tool, many have questioned its flexibility¹⁴, particularly for those that need to wash their hair - an exercise which will certainly last longer than four minutes.

毫无疑问，这是很有创意的节水工具，但是很多人质疑它缺乏灵活性，特别是那些要洗头发的人，洗头发花费的时间肯定会超过四分钟。

However, as it stands, the shower curtain is currently only an art installation and not available for commercial sale.

不过，浴帘目前只是一件艺术装置，并没有开始出售。

But the artist has told Huffington Post: 'I would love to develop it into a commercial product. People get very excited about it for lots of different reasons ... design, ecology, education, art.

但是这名艺术家在接受《赫芬顿邮报》采访时表示：“我很想把它变成商品。人们对它兴奋不已，原因不一，如设计、生态、教育、艺术。”

The light-hearted invention is part of the textile-based artist and educator's project, My Shower Curtain is a Green Warrior¹⁵.

这个有趣的发明是织物装置艺术家兼教育家的“我的浴帘是绿色战士”系列设计之一。
