Henry Cavendish establishes the gravity constant to determine the density of the earth. His apparatus was much less complex. He used telescopes and light to measure the small increments of movement in his apparatus. The apparatus consisted of suspended weights that attracted each other. There were many problems to face other than measuring small amounts of movement. Turbulence played a large role in the movement that left error. He dealt with this by building a ten foot by ten foot room which concealed most turbulence. Also, he measured known turbulence that occurred and use that to correct the data. This led to the gravitational constant that we have today.
The picture is a modern apparatus for presenting the effects of gravity.

The sun rises on a cold wintery day.
If you compare this photo, with the other one entitled "Sunset in East Tennessee", this is scientific proof of the phenomenon that the sun both rises, and sets, in the West.
Nobody believes me when I say this, but I have photographic proof here.
It's the same as when you shut off your cars engine in certain areas of the world, and the car will coast uphill, defying gravity.
Our planet is mysterious.
In case you're planning on landing on another planet, I made this handy chart to let you know how heavy you'll feel

"If anything, the night succeeded solely for the fact that on the ninth anniversary of the September 11 attacks, a capacity crowd of Milwaukeeans was treated to a “Russian” wrestler and a guy in a goat mask kicking the crap out of some surly, shifty-eyed “Arabs.” Never forget."

Close inspection of the Gravity Wheel reveals the logo for the one-time Epcot attraction Horizons affixed to the hub of the wheel. Horizons, which was located on the site of Mission: SPACE, featured a look at plausible future habitats, including ... space!

The attraction queue contains several items and commemorative plaques from past, present and fictional future space missions. Among the items on display are props from the 2000 film Mission to Mars, including the rotating "gravity wheel" from the predecessor X-1 spacecraft, a model of which hangs from the ceiling

I set out to construct this object by seeing what the largest number of 2-layer hexagons I could use for the faces of an icosahedron was with my current magnet count. That turns out to be 7, which can be arranged nicely with one in the middle and 6 around it. I then played around with various ways of folding those larger hexagons up, and arrived at this.
It holds together reasonably well, but gravity pulls it down so that it's a bit squat when sitting on the table.
In other news, the pictures I took a few days ago of the soft truncated dodecahedron I made a video of didn't turn out, since the camera was unexpectedly in fixed focus mode. I might remake it some time if people would like to see some better pictures of it.
'Gravity' was Aerial Edge's 2019 Spring Show, taking place in their venue at Kelvin Hall.
