Bobzilla: here's how you fix the double image problem
The spirit ball is spray painted with a bunch of silver paint to make it look more magical, I guess. Take some paint thinner (actually, I had to use "thinner for metalizer," because regular paint thinner wasn't strong enough) and wipe off the flecks of paint that are in the front area of the globe (the part that looks clear).
If you look closely at my video, you can see that when Leota's mouth opens really wide, it actually had that double image on the lower part of the globe.
Hope that helps.
