fuck that video, extremely big nope. i've gone through ice on a lake twice, was on the same day, first once through, then again getting back to land. shit fucking sucks, very nearly died from hypothermia, if i wasn't extremely fit back then, i wouldn't have to worry about hypothermia at all, i would just have drowned. everytime i tried to push myself up on the ice, it broke, again and again, finally managed to throw myself up enough to spread myself out over a larger area and get up from the freezing water. i had to do that twice, then walk 7-8 km back to civilization in -15 c. learned a valuable lesson, and i don't go out on the ice before new year ever again, no matter what. we had even measured ice thickness on a lower lake that this one was connected to, and the ice there was safe enough, but currents in the upper lake made it very different.
