Cuando el vidrio fundido cae al agua, se enfr\u00eda y solidifica r\u00e1pidamente desde el exterior. Al pasar de l\u00edquido a s\u00f3lido, el volumen del vidrio se reduce ligeramente. Dado que la superficie se endurece primero, el vidrio que a\u00fan est\u00e1 fundido en el interior queda fuertemente &#8220;estrangulado&#8221; o apretado por la fuerza de contracci\u00f3n externa.<\/p>\n<p data-sourcepos=\"19:1-19:174\">Posteriormente, el vidrio interior se enfr\u00eda y solidifica lentamente, pero como la capa exterior ya est\u00e1 dura, el vidrio interno queda atrapado bajo una fuerte tensi\u00f3n (esfuerzo de tracci\u00f3n), como si fuera estirado hacia afuera. Como resultado, la L\u00e1grima Holandesa tiene una superficie fuertemente comprimida, mientras que su interior est\u00e1 sometido a una intensa tensi\u00f3n. Este equilibrio de fuerzas tan particular es el secreto de la L\u00e1grima Holandesa.<\/p>\n<p data-sourcepos=\"19:1-19:174\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-55220 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2025\/06\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2025-10-31-4.53.32.jpg\" alt=\"\" width=\"539\" height=\"406\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2025\/06\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2025-10-31-4.53.32.jpg 866w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2025\/06\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2025-10-31-4.53.32-300x226.jpg 300w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2025\/06\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2025-10-31-4.53.32-768x578.jpg 768w\" sizes=\"auto, (max-width: 539px) 100vw, 539px\" \/><\/p>\n<p style=\"text-align: center;\" data-sourcepos=\"19:1-19:174\">As\u00ed se ve al observarlas con un polarizador.<\/p>\n<p data-sourcepos=\"21:1-21:213\">Gracias a esta tensi\u00f3n interna, la cabeza esf\u00e9rica de la L\u00e1grima Holandesa es incre\u00edblemente resistente. De hecho, \u00a1es dif\u00edcil romperla incluso golpe\u00e1ndola con un martillo! Sin embargo, lo sorprendente es que si se agrieta o se rompe la parte de la &#8220;cola&#8221; de la gota (por ejemplo, con unos alicates), toda la estructura se desintegra en pedazos al instante. Esto se debe a que el peque\u00f1o da\u00f1o en la punta de la cola libera la fuerte tensi\u00f3n interna acumulada, lo que provoca una propagaci\u00f3n catastr\u00f3fica de la fractura.<\/p>\n<p style=\"text-align: left;\" data-sourcepos=\"21:1-21:213\">Se recomienda hacerlo dentro de una bolsa de pl\u00e1stico y usando gafas de seguridad.
