Капли словно катаются по горячей поверхности: слой пара отделяет воду от металла. Это эффект Лейденфроста. Английские подписи.
These water droplets appear to skate across hot metal. This is the Leidenfrost effect: a thin layer of vapor forms beneath the water, separating it from the hot surface and slowing heat transfer.

В микрогравитации поверхностное натяжение и капиллярные силы направляют воду неожиданным образом. Реальный эксперимент на МКС. Английские подписи.
Water behaves differently aboard the International Space Station. In microgravity, surface tension and capillary flow can guide water in ways that look surprising on Earth. Watch it stretch, cling and pull back together.

На ките оказались более 137 метров рыболовной лески и ловушка весом около 61 кг. Кадры работы подготовленных спасателей у восточного побережья США.

A whale was carrying over 450 feet of fishing line and a 135-pound fishing trap. These real rescue scenes show trained responders working to disentangle it off the U.S. East Coast.
If you see an entangled whale, report it to local marine wildlife responders and keep your distance.

Одно прикосновение — и мимоза складывает листья. Специализированные клетки теряют воду, давление меняется, и листочки опускаются.
