《蜘蛛侠2》中，蜘蛛侠彼得·帕克用织网拦住了一列高速行驶的城铁。根据英国兰开斯特大学三位物理系学生发表在该校《Journal of Physics Special Topics》上的计算结果（PDF），只要正确锚定，蛛网真的能拦下高速行驶的火车。学生计算发现，为了拦下快速移动的火车，蜘蛛网需要承受30万牛顿的力。为了确保不会彻底裂开，蛛网需要吸收5亿焦耳的能量。如果网是达尔文树皮蜘蛛织的，那么这个不可能的任务真的可能实现。蛛丝的强度是凯夫拉尔纤维的10倍以上。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
