Here is a science teacher, Emily Morgan, author of Next Time You See the Moon, showing you how you can experience a moon phases demonstration in a dark room, using only a lamp, a styrofoam ball and a pencil:

I expected there to be a lot of photos of this recent eclipse, and maybe there were, but most of the videos posted are those that anticipated what was going to happen. I saw parts of the eclipse from L.A. but I couldn't stay up all night, so I missed most of it. But it was very impressive at about 4:00 am and at 5:30 am. I saw the blood moon (which is really a copper color, not red) and I saw a clearly curved shadow of the earth covering part of the moon.
.
This video recorded a live stream of the January 31st blood supermoon eclipse:
.

.
It's very long (over 4 hours) -- the eclipse starts showing up at 1:00 hour (the first hour is when the penumbra was covering the moon but photography doesn't let you see that due to brightness factor).
.
They show images from apparently 3 different locations so you'll see the moon orientated differently and it's all mixed up. Not a very smooth compilation, but at least it is chronological. Some videos do not give chronological accuracy at all. So this one is much better in that respect. You can skip ahead and miss a lot of the boring slow images.

Wednesday, February 7th, will be a day that gives everyone in the Americas a great opportunity to see first hand what the relationship is between the sun's distance from the earth and the moon's distance from the earth.
.
Last month there were very good viewing days, and this will be yet another one.
.
For those who want to know the truth, that is.
.
The moon will reach its last quarter phase Wednesday morning at 7:55 in the Pacific time zone.
.
That means it will be 10:55 am in New York and the Eastern time zone when the moon's phase reaches the last quarter.
.
Central time will be 9:55 and Mountain will be 8:55.
.
We know all this IN ADVANCE, whereas flat-earthers don't know anything about it in advance.
.
This will be during broad daylight hours, all over Canada, the USA, Central America and South America.
.
Why the whole western hemisphere?
.
Because the moon's phases always show themselves the same all over the world, wherever the moon is visible.
.
If the earth were "flat" that would not be the case.
.
It also would not be the case if the moon were only a few thousand miles away from the earth.
.
If the earth were "flat" you'd see a quarter moon in one place and a gibbous or crescent moon in another place.
.
And if the moon were very close to the earth as flat-earthers claim, you'd see part of the dark side of the moon under it.
.
But we never see the dark side underneath the moon, it's always on the right side or the left side, never on the bottom.
.

.
Just one more day to go!
.
Every month we are given two chances to test our perception for how far away from earth the sun is compared to the moon.
.
We are given two quarter moons each month, a first quarter and a last quarter.
.
Sometimes we get the last quarter early in the month and the first quarter later, and this is one of such times.
.
But the convenience of viewing is not always so good as this.
.
Tomorrow will be one of those days when it is really easy to see both the quarter moon and the sun in the sky at the same time.
.
The only variable left is whether you will have clear skies so you can see the moon real well, and the sun.
.
We can predict by the times shown what the position in the sky will be of the moon and the sun.
.
The last quarter moon occurs at 7:55 am tomorrow morning, meaning the sun will have been up for one hour.
.
The sun will be just coming up over low hills in the distance, or will be about 10 degrees above the horizon line.
.
Since the moon is a quarter moon we know it will be close to a right angle from the sun.
.
Therefore the moon will be at about astronomical 1:00 in the sky, just to the west of directly overhead.
.
Of course, it will also be in the line of its orbit, which is currently 5 degrees north of the ecliptic.
.
This will be as viewed from the Pacific time zone (UTC -8 ).
.
If you're in the Mountain time zone, it will be later, 8:55, Central = 9:55, Eastern = 10:55 am. 
.
So everyone in America gets a clear view of the moon's quarter and the sun, if you have clear skies tomorrow.
.

I thought the natural physics of a liquid was to conform to its container (much like a cat), not simply find level.  

.
There is only one degree of curvature in every 70 miles of earth's surface - too small to notice normally.
.
Anyway, looks like everyone missed another quarter moon opportunity.
.
There will be more, two each month.
.

.
Saturday, March 24th will be your next opportunity to measure the angle between the quarter moon and the sun.
.

.
The OP video is a good one to see when you're thinking about where the sun is during a full moon at midnight.
.

So without.  Nothing here proves earth is a sphere.

.
This week is when the full moon meets Catholic liturgy, because there was a full moon when Our Lord suffered in the Garden of Olives.
.
Catholics can step outside, or go to an olive garden, and have the full impression of what Our Lord saw that fateful night.
.
Notice the full moon doesn't have any shadow underneath it, which it would have if the earth were "flat."
.
If the sun were on the other side of a "flat" disk-earth, on the lowest part of the moon would appear a dark shadow where it's out of reach for sunlight, just as part of the moon appears in shadow in the crescent, quarter and gibbous phases.
.
No, the full moon is always FULL -- not sometimes, not usually, ALWAYS.
.
This is one of the MANY ways we can make first-hand observations that prove the earth is not "flat" but is rather spheroid.
