Stopping a quad bike rolling down a hill In Alberta in the United States, a man riding a Suzuki LTR 450 quad tried to climb a hill, but lost control of his vehicle almost at the top. The quad rolled down the hill and headed towards a group of stationary quad riders.

Cavitation in a glass water bottle Cavitation in a glass water bottle being hit by a hammer. Cavitation is a phenomenon in which the static pressure of a liquid drops below the boiling pressure of the liquid, leading to the formation of small vapor-filled cavities within the liquid. At higher pressure, these cavities collapse and can create shock waves that can damage the container. Video in slow motion at 82.000 frames per second from them "The Slow Mo Guys".
