foam困难

In the 1960s, the Italian artist Piero Gilardi began to create hundreds of bright, colorful foam pieces.

20世纪60年代，意大利艺术家皮耶罗·吉拉尔迪开始创作数百件色彩鲜艳的泡沫作品。

Those pieces included small beds of roses and other items as well as a few dozen “nature carpets” — large rectangles decorated with foam pumpkins, cabbages, and watermelons.

这些作品包括小型玫瑰花坛等物品，以及几十块“自然地毯”——饰有泡沫南瓜、卷心菜和西瓜的大块长方形地毯。

Unfortunately, the polyurethane foam he used is inherently unstable.

不幸的是，他使用的聚氨酯泡沫本身就不稳定。
