Pee-riodic tables

The source of this image is a reddit post which included only the following explanation, "The bathroom in our science building has the periodic table in tiles".

I need more info. 

Where's the building? I assume it's a university science building, but there's no info provided.

Why do the metalloids seem to continue diagonally down from the table itself?

How old is the bathroom design? Nihonium (element 113) is the last element shown, and that was created in 2003 or 2004 with the discovery not adjudicated until 2015.

Why do the metalloids, halogens, and noble gases get to continue upward into the border design?

(Oh, and I can't take credit for the title joke. That came from the first comment on the reddit post.)

Modeling a Gas With Magnets

That works surprisingly well, though I'm terrified of magnets as large as Cody is using to vibrate the individual 'molecules'.

Floating stick man explained

I know, long-time blog followers have seen the floating stick man phenomenon before.

...but they haven't had Steve Mould explain why it works before, nor have they seen it used to animate an alien abduction.

How Do Dry Cleaners Clean Clothing

tl;dr - They use solvents with weaker IMFs that water - some of which are nonpolar.

It's been a big improvement over the ancient Roman 'dry scouring' which was based on fuller's earth, lye, and urine-sourced ammonia.

The solvents used have varied over time from turpentine, gasoline, benzene, and kerosene (all highly flammable, carcinogenic, and stinky leading most dry cleaning facilities to be located outside of densely populated cities) to tetrachlorethylene (which is less flammable but toxic to plants and animals and can lead to neurological issues like Parkinson's disease).

So, dry cleaning isn't remotely 'dry.' It's just cleaning with gentler machines using solvents that evaporate more quickly and readily than does water.

Liars...
