Sorry guys, I don't know the specific name of the prop in the show, lol. I thought it would be a nice easy prop to make. I started out with a beach ball that set me back about $3 and I first tried plaster as a coating over it (which sucked) and I switched to bondo. $9 worth of bondo later I had a small moon! I lightly sanded my work with an orbital sander and made the lettering out of foam. The letters are just temporarily stuck on (I know they aren't placed properly) I will most likely thin out the letters a bit and I'll be covering the globe with a stringy texture out of hot glue and covering the letters in plastidip and then painting/airbrushing it!
