Things invisible! (when in water) Porous Concrete! Sand that cant get wet!
Continuing my trend to post science/tech I find interesting, this time I thought I would post my amazement at some of the
materials we have available these days. There's a lot of them about, so consider this part 1 of this theme.
Mostly I just looked for a interesting video demonstrating a material I knew existed. So some of these are from companies that sale them;
---
Polymer with identical refractive index to water;
https://youtu.be/IPK2m0qRZx4?t=37
This ones sold as a toy - effectively, it becomes completely invisible when placed in water.
--
One that got fair coverage already but still cool, is Ventablack, a material that reflects almost no light - even if a lazer is pointed straight at it. This gives the impression of it being a "hole" in space, as its implausibly dark and gives no hint to its shape when looked straight on:

--
Concrete is fairly fixed in our heads as being a pretty solid thing, yet versions exist now where water will pass straight though it;

This is naturally very useful for drainage.
---
Hydrophobic sand:

Hydrophobic spray on coating:
https://www.youtube.com/watch?v=IPM8OR6W6WE
Hydrophobic materials are essentially ones that repel water.
Liquids will not naturally spread out on them, and rather be governed a lot more by surface tension.
As such they are really weird to look at and water on them seems to act quite unnatural. Pour hydrophobic sand into a liquid and the water forms a bubble around it rather then touching it - remove the sand and its still completely dry.
The benefits of hydrophobic materials, as seen in the second video, are essentially keeping things clean with little to no effort.
---
Thats it for now, stay tuned to for more random science & tech in your feeds! (or something)

Petition worth considering for UK folks.
3 months seems a big short to me, but it seems fair to have a time limit of some sort given how, unlike the US system, the UK doesn't really have a "VEEP" which the public knowingly elects together with the main candidate.
A lot of people seem concerned with how "democratic" something is recently - certainly it was concerns by some on the brexit camp - and yet, arguably now the uk has ended up with a unelected leader. This is not actually uncommon for the UK...but it still might not sit well with people.

https://petition.parliament.uk/petitions/137376
Notes on the petition: Like all petitions at the site 10,000 signatures gets a official response, 100,000 means it will be considered for debate in parliament.
We the undersigned ask parliament to legislate to require the calling of a general election within 3 months of a prime minister resigning leadership of his/her party.

It depress's me beyond belief that this sort of advance technology AND YOU ARE STILL USING ANIMATED GIFS.
WHYYYYY??
Please Google tell me why? Why cant Chrome support APNG? Why must we be doomed to this low-colour dithered hell for decades. The web could be so much better so easily. :( :( :(

(and yes, the app looks really cool)

Webm is also great.
I hate however this weird stalemate where neither has become standard.

Microsoft has opened up the platform behind its HoloLens augmented reality device, inviting partners to build their own products in different form factors and at different price points.

Of course, if people want much more awesome animation abilities
Krita 3.0 has just been released.
https://krita.org/item/krita-3-0-released/
Multiplatform, Opensource, utterly awesome painting program that can pretty much do everything you can think of - and it now can make animations. (which has pretty awesome potential when factoring in all its non-destructive editing functions. Oh and being able to paint high dynamic range frames in a animation is insane in itself)

So, three at sea, two on land.
Most of them seem in good condition.
Seems this is approaching a regular thing. Real delivery's to the space station without chucking most of the ship away each time.

As a semi-related thing I thought was cool. A few months back 6 different craft were docked at the ISS at the same time.
I wasn't even aware that was possible.
SpaceX pulled off its fifth rocket landing in the last seven months early Monday morning (July 18), this time bringing a booster back during a successful cargo launch toward the International Space Station (ISS).

Trump is now making up quotes of people praising him on tweeter.
http://www.cracked.com/blog/trump-having-twitter-conversations-with-fake-accounts/

I dont even know what this is at this point. Its like he is deliberately giving the US a intelligence test....or going senile?
I am curious to see how his supporters defend this one too. Its just so......nuts.

At least thats what I think, and fakeaccount@twitter agrees with me;
"Thomas is so on point! Hes the best!"
Donald Trump is the GOP frontrunner, and he is absolutely garbage at social media.

We just had a bottle of cider explode violently.
"cidre artisanal"
It had been in our cupboard unopened and just exploded shattering the glass everywhere.
If it was anywhere near us at the time it would have easily caused a serious injury.
If you have any bottles of it yourself Id suggest immediately move
them away from anywhere sensitive and keep your eye open for product recalls.
"Angry Orchard" is another brand that has had this issue and had a recall last year.
