demo

Water is flowing from the left side of the demo under an obstruction and over to the right.

If I add the slurry to one side of the demo, you can see how the denser fluid displaces the groundwater.

It seems pretty straightforward when you exaggerate it in a demo like this, but in reality the Bank Effect is not that well understood.

Another obvious difference between my demo and the real world is that we don’t normally having access to the top of the bolts to add nuts and washers.

The keynote was so brutal, mainly because so many of the live demos that they tried went about as poorly as they possibly could have.

Let’s try one more demo.

So, you’ll have to excuse the smaller glassware demo.

Those cracks are the important part of this demo, but I went ahead and increased the load until the beam failed because, hey, that’s what hydraulic presses are good for right?

Mother Teresa, you scored a 0.2 with a 18 to 45 demo.

As you can see from this 60 year old video from the Royal Institute of Science, this demo isn't exactly new.

The minimum speed to make sure lines stay clear is known as the self-cleaning velocity, and you can see why in the demo.

Now, you might have thought this was just an iPad thing 'cause we all saw this get demoed at the keynote in iPadOS 18, but it actually is on the iPhone, as well.

And it's unfortunate because the product is so cool, and I gotta give them props for trying to do real demos instead of faking everything, I guess.

And I’m using tons as a measurement of force on these beams, just because that’s what the gauge says, but the units are completely arbitrary to the demo.

Rock bolts are most feasible when you’re tunneling through jointed rock where you can put a little more space between the bolts, but this demo is just to show that it can be done.
