Underwater music A Danish music group, "Between Music". Five performers immersed in water tanks, playing custom-made instruments and singing, entirely underwater. This is an excerpt from the concert.
A bridge turns into a waterfall (Italy) Heavy rain was reported in the southern Italian province of Gagliano del Capo on October 22 as bad weather affected much of the country. This footage, shared by Bar Ristorante L’Incanto, shows water cascading from a bridge on the southern coast.
Tiger Mantis Shrimp Hunting Occurred on January 13, 2018 / Sulawesi, Indonesia We have been trying to find the best footage of underwater, amazing sea life!
Whale Shark Shows Off Impressive Mouth A massive ten metre whale shark is showing off his impressive mouth by ‘opening wide’ in this impressive and rare recording while feeding. The over-whale-ming footage was captured in the waters off La Paz, Mexico, by underwater videographer Stefano Ulivi, 42, who says the sight was a moment ‘everyone wants to capture’. The whale shark, a gentle giant of the ocean, swims into a vertical, upright position before filtering water for the plankton - some of the smallest microscopic prey. In the footage shot last year but recently released, Stefano got up close and personal with the world’s largest fish – that measured a whopping ten metres in length and with a 1.5 metre jaw.
Nuclear Reactor Pulse and Startup Compilation The blue light is known as Cherenkov radiation. It is similar to a sonic boom, but instead of an object travelling faster than the speed of sound, a charged particle is travelling faster than the speed of light in a medium. In this case, the speed of light in water is roughly 75% the speed of light in a vacuum. It tests the time-dependent properties of the fuel. Engineers use that data to predict what would happen if there were an accident at a large reactor Cherenkov radiation, also known as Vavilov–Cherenkov radiation,[a] is electromagnetic radiation emitted when a charged particle (such as an electron) passes through a dielectric medium at a speed greater than the phase velocity of light in that medium. The characteristic blue glow of an underwater nuclear reactor is due to Cherenkov radiation.
Essentially when light passes through different materials its speed can be slowed as the photon makes it way through the medium.
An air gun underwater This is a new invention I created, it is being manufactuered by H2Odyssey and will be available some time in September for around $130 at the store. Here is Underwater footage of two Scuba Divers shooting each other with Bubble Rings. The device is a Torid Pulse, it is a sort of Bubble Gun that attaches to the low pressure port of your scuba tank, just like a back up regulator. It will shoot round Bubble Rings up to about 35'. The device is easy and fun to operate, is low maintenance and does not seem to harm the environment, fish are indeferent and it only uses compressed air. On a typical dive of about 30' deep, you can stay submerged for about 45 minutes and still shoot 300 shots or so with out issues of air exhaustion.
