Air pockets in palm votives. I hate those stinkin' air pockets. Even when you poke relief holes, there are still air pockets in the votive. In fact, when I repour, I use a small poker and kinda dig in the relief hole til all the air bubbles come out. If you dig too much, the cooled wax that comes up from the hole will mar the top of the votive. But, it's better than having a votive that is lit and then goes shwoooooosh when it hits the air pocket.
