无底洞穴 在希腊亚各斯古城有一个无底的洞穴,它每天要吞噬3万多吨海水,却从未向外溢出。有人认为,海水可能从下面流向周围的湖泊里,便将无数的红色塑料小颗粒灌入洞穴,然后,人们在周围的河流、湖泊里寻找塑料颗粒,但每次都未发现它们的踪迹。 变形洞穴 尼加拉瓜圭纳附近的丘科米尔镇,有一个直径3.45米的古怪洞穴。上午,洞口呈椭圆形;下午,成了不规则的长方形;到深夜,又变为正方形;而到次日凌晨,却又变成了原来的椭圆形。如此循环不止,到此的游客无不感到异常惊奇。 Bottomless Caverns There is a bottomless cave in the ancient city of Aegis in Greece, which consumes over 30,000 tons of seawater each day and never spills out. Some people think that seawater may flow from the bottom to the surrounding lakes, pouring countless red plastic granules into the caves, and then people look for plastic granules in the surrounding rivers and lakes, but no trace of them is found each time. Deformation Cave Town of Chukumir near Nicaragua, with a 3.45 meter diameter quirky cave. In the morning, the hole was oval; in the afternoon, it became an irregular rectangle; in the middle of the night, it became a square; and the next morning, it turned into an oval. This cycle is more than that, all tourists are surprised.
