The eggshell break points polluters does exactly what it promises. It is enough to lift the ball and drop again. I had seen in a video on YouTube that this was done twice. But it is enough and you can actually once the lid only with the help of nails stand out. The breakline is completely smooth. If you try, the ball drop for a second time, a ripped the eggshell the bottom half with me. Maybe it is also due to the different thickness of eggshells. In my case, a process for a perfect result would have been enough.
