I lived in Cape Canaveral during the shuttle program and was fortunate enough to watch all but 5 launches live.

An excellent video with scenes I thoroughly enjoyed in slow motion and HD.

A brief mention in the video about the 6 seconds from when the main liquid engines ignite until the solid boosters ignite is called "twang."

When the main engines ignite, the power causes the whole assembly to rock forward. It takes 6 seconds for the assembly to fall back to vertical again and then the boosters light up and away it goes.

Ok, let me start by saying I have a pretty low opinion of the whole "security theatre" at airports, etc.

That said, I've always thought that "pat-downs" are friggin' pointless unless you're going to do the whole body.

I've had the occasional search myself while travelling and it's almost always completely perfunctory. If I was actually carrying a weapon or some mythical "dangerous liquid", I could easily have stashed it in my crotch or my shoes.

Basically, either you actually do a body search (including genital area), or just admit the whole thing is fucking bullshit and let us on our way.

They've hooked up a power source to the orange which is why it is cooking as it sits there and starts spilling liquid on the table.

I was waiting for the reveal and disappointed that they didn't show what it was hooked up to.

The technology to load shift is available, but getting it developed and implemented is one of the components that is missing from the overall power strategy in Aus.

Energy companies, like Ergon (Queensland) are actively trying to limit input, with a hard cap of 5kVa input for residential, and sometimes even as little as 3kVa in some more remote areas.

And while technology like liquid vanadium battery cells (long life, expandable by adding extra tanks of liquid electrolyte) exist, they are still prohibitively expensive.

There are plenty of solutions, but little appetite from the companies and governments, and very little knowledge among the end users. So while we're throwing cheap Chinese panels on rooves with gay abandon, I think it's a little early to brag about what a rampaging success Aus solar is because "lots of panels yo!".

It sinks the rocks and brings up liquid, so when you go over it, the tool doesn't get stuck like it does when you pre-edge, so you end up much smoother.

Same.. I have seen this tear drop shape when liquid solids hit water, but heard nothing about its properties. It is pretty amazing but I wish they could solve the tail construction. Like.. what if they cut the drop before it hits the water so that there is no hairlike tail? Now we just need teardrop shaped phones so we can use this as glass. -_-

Water normally has some dissolved air in it, which is expelled and trapped when it's frozen leading to the white spots in the ice. To make clear ice you need to avoid the dissolved air being trapped in the ice.

One way to do this is to boil the water before freezing, which reduces the amount of dissolved gases.

What I think is happening here is that freezing only part of the water, and relatively slowly, lets the dissolved gases remain in the liquid part of the water.

Uhhh, didn't the control test with water prove that it's primarily the liquid nitrogen causing this? Has little or nothing to do with the Coke in the bottle. Anyway...

Don't mix Coke and liquid nitrogen?

Hells no, you obviously use plain tap water!

Wax is a lubricant, or at least it can be. Not to be confused with wax for surfboards. My theory is that in liquid form it gets sucked into the threads via wicking action and prevents the binding of rust on rust when trying to turn the nut, but that's just my 2 cents. This probably won't work for nuts that are over-tightened, just ones that are rusted in place,

Hmm... you make a compelling argument Maybe I just got sucked into the marketing! Matthias's explanation even points out that venturi pumps are inefficient, and used where you don't want the liquid you're pumping anywhere near the inside of your pump.

The big disadvantage of using a small fan is normally that you get more noise, which I suppose might be overcome by the ducting.

I don't see any reason you couldn't use a larger fan in the setup though... you should even be able to use a box fan.

Clearcoating this stuff would remove its blacker-than-black properties. It would then start to reflect light. At which point, why would you favor this expensive shit over regular paint? I haven't seen details on how the sprayable Vantablack is applied, but if it were mixed into a liquid for application, it would have the same problem, unless, somehow, the surface of the hardened material were burnt away, evaporated off, or chemically reduced so that the carbon material could protrude from the substrate, that may allow the light absorption properties to persist. But I don't know how they accomplish that, other than they say it's a complex process that requires a specialist. I still wouldn't try brushing up against it, just like I wouldn't try sitting there inhaling paint fumes after painting a car. There's a reason precautions are taken in that process as well. I just know that something small and damaging enough to burst cell membranes sounds like something I wouldn't want in a product I'm handling with direct contact with my skin, or with any remote possibility of it rubbing off and getting into the air.
