砂を液状に…カヌーもこげちゃう? 流動床、応用に期待

角拓哉 2017年5月16日08時50分

砂を液状にするという、ものつくり大学(埼玉県行田市非常勤講師の的場やすしさん(53)と、同大教授の菅谷諭さん(56)の研究が関心を集めている。砂の中に空気を送り込み、液体のような状態にする「流動床(りゅうどうしょう)」と呼ばれるもので、アトラクションやトレーニング分野への応用が期待されている。

 流動床は、砂を入れた容器の底から空気を送る。砂にかかる重力と空気で浮かせる力が釣り合ったときに液体のような状態になる。

 研究室では、縦1・7メートル、横1・1メートル、高さ60センチの大型水槽に1トンの砂を入れて送風。手をいれれば水の中と同じような感触に変わり、底に沈めたボールも浮かび出る状態になった。川下りの映像を見る「ヘッド・マウント・ディスプレー」を頭部に装着し、船に見立てた小さな水槽も浮かびあがり、カヌーの疑似体験もできた。

What the fuck is happening

To all those who are wondering, while I don’t speak the language I do understand the science behind this video.
Basically what is happening is they’re blowing a bunch of tiny bubbles into the dry sand, what this does is make all the particles move around each other actively making the sand act as a fluid.
So while the sand is aerated you can easily move things around in it, but when it’s not, it settles and returns to a more solid mass.
It’s the same idea of how real life quick sand works, just substituting water for air.

It’s like the quicksand episode with the mythbusters but instead of water, they used air.  SCIENCE!

look. i don’t think my stretch marks are beautiful. i don’t think they’re tiger stripes or natural tattooos. i don’t think my acne is beautiful. i don’t think the bags under my eyes are beautiful. i just think they’re human. and i don’t think i have to be beautiful all of the time in order to be accepted and loved and sucessful. i don’t think every small detail of my outer appearence needs to be translated into prettiness.

Boozhoo (hello), my name is Ken, I am a disabled Ojibwe artist from northern Wisconsin. I am writing this post because I am having a hard time making ends meet and any donations I could possibly receive at this time would be greatly appreciated. Recent events have left my bank account depleted and my cupboards bare, I have some food but it will not last and I still do not know how I will cover all the utility bills.

I do have PayPal, that is really the best way to donate at this time, the email I use for that is: baapimakwa@gmail.com, or you can click here.

I know this is like a really controversial opinion but fat people deserve to be treated like a human beings whether they’re healthy or not

This ties into treating disabled people like they’re inhuman. It’s the same principle: “you’re like this because you’re too immoral to help yourself, otherwise you’d be healthy”
