Since when is it a crime to defy the law of gravity?

Seems not too bad, relatively speaking.

Babies after 9 months of floating in in low-gravity take like a year or two to get walking.

Dropping like flies. Gravity vs Friction.

Probably the first time that fish has ever experienced gravity.

Oh, and a spear too.

If that moon or other planet over the horizon isn't part of the plot line, I give it a thumbs down.

The gravity of the visible planet and the earth like planet the characters are on would be on a collision course. I suspect the environment and the characters should already be rising or at least be feeling the effects of the planet over the horizon.

That, on its own, would be a bigger story line than whatever is going on in the clip.

If Neil deGrasse Tyson was dead, he'd be rolling over in his grave.

Its a cute prototype that stretches the imagination but is a wholly improbable design to find its way to Mars.

The weight and dimensions alone would make it very, very difficult to de-orbit onto the surface of mars. This thing weighs: 5,500 lbs. (2,500 kilograms).

Its not going to be very economical to get it out of earths gravity and into orbit just to start, forget about the energy it will require to get it moving towards Mars.

Some people spend a lot of time and money to learn about gravity. Either way, you pay the price.

The sand certainly helped it, but yeah, low center of gravity FTW.

Can be! It depends on the contents of the container and how air-tight its construction and materials are. Generally materials packed for transport are supposed to be strapped or otherwise held in place so that they don't shift and upset the transport vehicle (see the 747 that crashed in the Middle East when its cargo shifted...). But that's just the stuff that was meant to be in the container. Every ship has to contend with the risk of water ingress. Un-contained water in a vessel forms a "free surface" and the so-called free surface effect applies. That's where that material can and will move based on gravity, often making a bad situation much much worse. Imagine water in a tank (itself a free surface) vs. water sloshing around the cabin of a plane. This is what usually causes ships to capsize: water gets in and isn't contained, so it can move tremendous amounts of mass anywhere it wants to go -- usually in the direction it's already going. Calculations of ship stability for things like cargo loading and ballast assume minimal free surface in the ship, because you have to. That's how ships stay upright and afloat.

How does this apply to lost containers? Depending on how watertight the container is and how well strapped in the contents are, some amount of water may get in and form a free surface. This free surface will move around until the container finds its equilibrium which may or may not be watertight and less dense than the water around it, which defines whether it floats or sinks and what direction it faces when it does.

A container with a lot of weight on one side but otherwise watertight will stand upright and perhaps still sink (like the one at the end of this video). A container with well-distributed weight would tend to end up flat. Whether it sinks or not depends on whether it's watertight and what its density is -- the weight of the container displacing ocean vs. the weight of the ocean it displaces.

Sadly, a significant number of containers end up at the worst possible density/displacement where they float just at or near the surface and lay in wait to devastate passing ships, regardless of the orientation of the container itself.

Well, the wind could NOT EVER blow the wind into the shape of a sand Castle, because both the Humidity and Gravity are working against it. Even if there was rain or moisture that perfectly conditioned the sand to stick to itelf in the perfect consistency, then the wind couldn't quite blow it around in the way it would need to. And of course Gravity would always cause the sand to fall to it's lowest points.

I know I'm being picky here, but this just stood out to me.
Everything else in the video was engaging.

Not just throwing rocks, but---what is the practical application of this? As a pleasure craft, maintaining all those extra hydraulics would drive maintenance expenses through the roof from the perspective of a recreational boater.
I'm also concerned about reliability, elevation of center of gravity, response to being sideways in a seaway... the second half with the outrigger "sled' maybe would have application in military stuff? Air/Sea rescue?

I remember my dad driving me in to town on a school day when we hadn't realized that school had been cancelled because of icy road conditions.

He could drive OK (very very carefully and slowly), but after we discovered that school had been cancelled we parked across the street from my grandma's house and found ourselves unable to walk over the crest of the road. Probably just 1-2 inches higher in the middle than the sides for drainage purposes, but with the perfectly smooth fresh ice, that was enough to make it pretty much completely impossible to "climb" up that very slight incline.

Looks like gravity and adhesion to the tree are causing the same thing for this guy...

Uh, what? Nobody said that at all. It is neither a "classic example" nor an assumption. The trajectory has been tracked since it was discovered, which is hyperbolic around the sun, and the speed of the object is such that there is no way it could have accelerated to its current velocity due to the gravity of our sun alone, hence it has to be interstellar, picking up kinetic energy from another system outside of our own. The orbit is not improbable, it is unusual compared to trajectories of asteroids that exist within our own solar system. Sharpen your crayon there bud, and stop trying to impress people with your new thesaurus for hipsters (come on, "undergird"?? Really?)
