论文摘要
“啤酒”是一种众所周知的恶作剧，一瓶碳化的液体从上方击中另一瓶碳化液体，通常结果是下部瓶泡沫超过了，而上层泡沫则没有。尽管已经调查并有充分的文献研究了导致下瓶中泡沫过程的物理学，但迄今为止尚无解释，为什么上瓶几乎没有产生泡沫。在本文中，我们描述了两个瓶子完全不同行为的原因。
"Beer tapping" is a well known prank where a bottle of carbonised liquid strikes another bottle of carbonised liquid from above, with the usual result that the lower bottle foams over whereas the upper one does not. Though the physics leading to the foaming process in the lower bottle has been investigated and well documented, no explanation to date has been provided why the upper bottle produces little to no foam. In this article we describe the reasons for the entirely different behaviours of the two bottles.
