Stagio,

When this happens, take and twist the cup into the base a little bit deeper. This helps build up the pressure a little more and should help get that rolling boil. Also, what color/kind of powder paint are you using? White, blue, browns, watermelons, and blacks are a little heavier than the other colors and will not "boil" as much as the flourescent colors. Give that a try and let me know how it works. Thanks again and let me know if there is anything else I can help you with.

Thanks,

Benjamin
