Lyke everyone that saw the movie,I wanted one of my own. So thanks to others, I found a way to make one.
Step 1: What You Need
This is a standard Styrofoam ball. It is better to go to Hobby Lobby and get the one that has two in a pack. I believe it is a dollar or two cheaper than what you can get at Michael's.
Other items not shown in picture (sorry)
Paint black and a grey or metallic silver. depending on how close to metal you want it.
hobby knife or styrofoam cutter plus
and lastly patience (very important if you want it close to how it looks in the movie)
Step 2: Laying Down the Design
I will put two steps in one for this since you can do both at the same tyme if you would lyke.
First, get a couple of good pictures of the item. I paused the movie a lot and took pictures of it (how I lyke to get my references). Then take the permanent marker and draw it on the ball. This is where the patience comes in. Mines took almost an hour because I am a tad bit OCD about my props, and this one has a lot of details.
Once satisfied, use your choice of cutting instrument to remove pieces to create the craters. My first orb I used a hobby knife, it got the job done but the holes were a bit more wider than I lyked. The second one I used my styro cutter, not only did it melt my problems away, it also made smaller holes and they where deeper.
You will see the differences in at the end.
Step 3: Creating the Depth and Top Color
On this part you are just painting the whole ball black. Use whatever means you want, just not spray paint! I hear that it will melt the styrofoam, not sure if that is true but I didn't want to find out :-p. I just loaded some paint in my airbrush gun and went crazy. Get the whole ball, just in case you miss a spot it will not be whyte and noticeable.
Lastly, paint the top grey or whatever color you picked.
AND YOU ARE DONE
Step 4: My End Results
The orb on the left is the one I used a hobby knife with.
The orb on the right is made with the styrofoam cutter.
I hope you enjoy
