Dolphin enjoying a bow ride

BSR says...

So what you're saying is, the Dolphin is basically surfing without a surfboard on an underwater wave created at the bow of the boat.

I can live with that.

Haven't Googled anything, but I think it's like ground effect in airplanes and helicopters. The dolphin is pushing against a horizontal "column" of water the ship is pushing in front of it. Allows it to move along with little effort.

I would think that, to the dolphin, it feels like how a dog does with it's head out a car window. All the benefits of moving fast, with almost none of the effort.

Underwater Eco Park-Rio da Prata

Payback says...

I'd think it would have mostly to do with the water being clean to begin with, and flooding extremely slowly.

Probably a Hell of a lot warmer than this place:

Wow, I'm a bit surprised the water is that clear after flooding.

Failing at Normal: An ADHD Story

newtboy says...

The best compliment I've ever gotten was accidentally overhearing someone say "Newtboy doesn't think like normal people."

Put the tree underwater, the fish will outclimb a monkey.

Houston Cop To Rescuers-"We've Had Enough"

littledragon_79 says...

If he is "following orders", then the top brass needs to get their shit together. There's no reason they can't organize the volunteers and dispatch them so they know who/where they are and what areas have already been helped. But I guess when your town's underwater, fuck help from Yankees.

Part of me wishes the driver would have just said, "There's a nice way to do that". I can't speak for the officer, but on it's face the interaction is shitty. Maybe he's super stressed about his own stuff. Maybe he's upset about having to help others and no one to help him. Maybe he thinks his orders (if there are any) are really stupid and is at odds with his superiors.

Whatever the case, ultimately he ends up doing a poor job of representing his dept., the city, and cops in general. Hope he and others learn.

Exploring the deepest pool in the world on a single breath

CaptainObvious says...

Y-40 "The Deep Joy" pool first opened on 5 June 2014 and was designed by architect Emanuele Boaretto. It is 40 metres (131 ft) deep, making it the deepest pool in the world. It contains 4,300 cubic metres (1,136,000 US gal) of thermal water kept at a temperature of 32–34 °C (90–93 °F).[4] The pool features underwater caves and a suspended, transparent, underwater tunnel for guests to walk through.

Kid almost drowning in a public pool, nobody notices

lucky760 says...

And the title says "almost drowning" but the boy was underwater and lifeless for a few minutes, so I really, deeply hope the title is accurate.

If you go to beaches, this is worth a couple minutes

One thing I don't like about this safety announcement is that it makes it seem like rips as these underwater murder machines just lurking out there trying to kill you.

There is nothing inherently dangerous about a rip current per se. Surfers use them all the time to get out quickly into the lineup quickly without having to duck dive the heavier sets.

The real danger of rips is to inexperienced or poor ocean swimmers. The rip can carry you out to water that is too deep to stand in very quickly, so if you're not comfortable floating or treading water for long periods that's going to be a big problem.

Most people drown because they panic when they realize they can't touch the bottom and try to swim back against the current to get to a place where they can stand again. In their panicked state they forget about floating or treading water and exhaust themselves. As long as you swim perpendicular to the current you should be fine. The number one mistake people make is that they forget to stay calm and take breaks by doing the side-stroke or treading water until they're ready to do the crawl stroke again.

All that said, lateral rips (rips that run parallel to the shore rather than out to sea) are some scary shit, as they can move basically as fast as a river. During lifeguard training in my younger days I got caught in one while doing a training rescue and was swept in literally seconds into a wooden jetty. Thankfully I was able to ride the crest of a wave up to the top of the jetty, pull myself up, and then sprint down back to the shore before the next set of waves washed me back into the ocean and carried me even further down the shoreline. After getting back, I took a lot of shit from my instructors and peers for nearly having to be actually rescued during a training rescue.

What If We Have A Nuclear War?

jimnms says...

I call bullshit. There have already been over 2000 bombs detonated for testing. Though most countries stopped doing surface, ground, underwater and atmospheric tests after the NTB, that still leave a lot of bombs detonated on the surface. I had a quick look at just US tests, and in the late 50s through early 60's, we were setting them off like fireworks on the 4th of July, with almost 100 detonations at the Nevada Test Site alone between 1962-1963.
