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.

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.

Goodbye Timmy

This made me remember digging holes to see how far down we could get.
This would have totally worked.

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.

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.
