For this weekends Brandon Folk, Music and Art Festival, I set up a little display of cosmic proportions on the festival grounds amongst the trees. My first time really doing something like this. It shows the a scaled down version of the exact scale between the sizes of the Moon, Earth and sun along with the correct distance that they would be from each other.
I wish it could be more hands on, but that would have been I bit too delicate in this environment. I do have available, a simple model kit that I manufacture, that contains this delicate orbital structure. It's an excellent educational device.
