This is a high resolution physical model of the shape of the earth where the surface is distorted to show the strength of gravity at each location. The further out the surface is, the stronger the gravity at that location.
I made this for my son's school project on gravity. I used a grayscale map of the gravitational field data from the NASA GRACE mission and used Blender to wrap it around and displace the surface of a sphere. Plan was to color it to show the different gravity strength areas but that may not happen.
Organic supports were a lifesaver! Just a little roughness at the very bottom, but the rest of the supports worked really well. I made an initial much smaller test with an integrated stand, just the base of a cone poking out from the bottom, but going without that for the bigger one worked out well.
