Advanced Sonokinesis

When you have advanced enough and are able to produce powerful sound waves, it's time to move on. With strong enough vibrations, it is possible to shatter glass. This can be done by packing the sound waves into a large ball and throwing it at the glass. The larger the ball, the better. This is because you have high sound frequences packed in one place; several of them. But if you are trying to break small glass structures a large ball isn't necessary. Good luck and enjoy.
