Video: Winter Cave Diving in Sweden

First discovered back in 1979, the Dolinsjö Cave is located underwater, making it extremely difficult to explore. But each year, a team of divers visits the cave during the winter, continuing to map out its depths in an attempt to determine just how large it actually is. So far, they've gone as deep as 1.7 km (1.05 miles), and have yet to locate the end of the cave. In this video, those divers take us along on one of their expeditions, giving us a look at the efforts they make in the name of exploration. It is a fascinating experience for sure, and I give these men a lot of respect for what they do. It can be very dangerous, and yet they press ahead into the unknown none the less.

Video: GoPro Camera Falls 3000 Meters While Recording

This video was actually found on a GoPro camera that someone stumbled across in their backyard in Sweden. When they took it inside they found the memory card was undamaged, so they examined the footage. Apparently it was dropped by a skydiver from about 3000 meters (9842 ft). The camera then plunged to Earth, recording the whole time. It also began to spin at ever increasing speeds until the ground looks like a mesmerizing pattern without any distinguishable features. That is, until it smacks into the ground, and continues to record while sitting in blades of grass. I guess this clip is a testament to how tough the cameras are, but be warned. Some may find the long drop to the ground to be a bit dizzying.

Video: Flying a Snowmobile Off a Mountain in Sweden

What do you get when you add a para-sail to a snowmobile? Why, a flying snowmobile of course. That's exactly what the team in this video did, and then they flew it off of a mountain in Riksgränsen, Sweden. The results pretty much speak for themselves. This is definitely a good shot of adrenaline for a Monday!
