Popping them out is a relative term. In my limited experience in pouring, Popping them out doesn't happen for the most part. I poured a hundred for someone earlier this week, first in a long while, and I did good to get 6 out of 8 to cooperate. I got em done but I think I need to smoke the mold again. I think once I get back into it more I'll smooth out and things will work fine.
