The World’s Largest Air-Horn

There’s a significant amount of science-stuff in this video which features someone named Mark Rober constructing a giant air-horn.
Yep, it’s loud, but you’ll also know why it is as loud as it is.

Planes, Rocketships, And Now (via XKCD)

Thoughts like this one give me pause.
I don’t know what they prove, but they give me pause.
Mostly I’m disappointed that we don’t have flying cars yet.
I also wonder if one day gaps like this will measure humanity’s first flight with our first steps on the moon, and the fact that noone’s been back to the moon in over that period of time. Surely one day we’ll return to space.

Your Brain On Cats (via Inverse Health)

Well, normal brains on cats, anyway.
A phd neuroscience candidate and (budding cat-lady) explains the effects that kittens have on human brains.
Seems as if cats have basically turned themselves into a drug.

Why Do Showers Suck? (via Mental Floss)

Ever had a shower in a shower stall that has a shower curtain and wondered why the shower curtain seemed to develop a life of its own, wanting to attack you and cling all over you?
Spoiled younger people probably don’t even know what a shower curtain is.
Anyway, great minds are trying to work out why.
This Mental Floss article contains some of the latest theories.
It seems like folk have been wondering for a while.

Liners have a tendency to billow inward during showers, enveloping themselves around our calves and forcing us to swat them away. As problems, go, it’s fairly innocuous. But that doesn’t mean science hasn’t tried to understand the physics behind the phenomenon.
Back in 1938, Popular Science theorized that liners were behaving badly as a result of air currents. When hot air from the warm water rises, cold air around the tub seeks to replace it, causing the liner—which is in between—to grow agitated. This explanation seemed to satisfy people for a while, until someone pointed out that the liners tend to move even during a cold shower.

Lighting 10,000 Sparklers All At Once

Ever wondered what happens if you light 10,000 sparklers all at once?
Maybe I’ll play this video before I go to bed well before midnight tomorrow.
Shiny.

Solar System To Scale

As Douglas Adams wrote, ‘Space is big. Really big. You just won’t believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist, but that’s just peanuts to space.’
This video demonstrates that truth, as a scale model of the solar system is created on a Nevada lakebed.
The sun and planets are sized relative to orbiting distances.
The effect is compelling.
