It is Known as the "Pool of Death"

Mordhaus says...

It is now known as Queen's Bath, but it isn't the original. The original one was destroyed by lava in the 80's, so they just renamed the pool of death.

They are definitely locals and skilled swimmers. Others have died during the winter when the surf is routinely high, like in this video.

Those are Kauai locals swimming in Queen's bath.

They know what they're doing. Here is another video .

Solving By Using 'Extreme Case' Puzzles With Physics Girl

newtboy says...

In the opening question she blew it. What if the rock is lava rock, which is LIGHTER than water? That means you can't figure out the answer without knowing the density of the rock.
Archimedes equation is only useful in figuring out weight for things that are buoyant. Anything more dense than water (or whatever medium you're in) will only displace it's own volume in water, not it's mass.
That's why I think the wood block should weigh more in a vacuum. It displaced more air, so was more buoyant, and so had more buoyancy to lose. It seems to me she set it up poorly again, because if they weigh the same in air, but are different densities, they would seem to need to have different masses to achieve balance, but she said they have the same mass, but I think she should have said 'they weigh the same'....just as @Barbar and @Stormsinger indicated above.

Is Glass a Liquid?

bremnet says...

Glass is a fluid and a liquid (liquids are a subset of fluids). All window glasses will, given enough time, flow. The rate dependent deformation of the glass is described by its viscoelastic properties. Many stained glasses and all lead based glasses behave more viscously than elastically when compared to their modern counterparts, and thus appear to flow more, when the reality is that they just flow faster.

And lava is in fact a type of soap.
