Typically with broken glass artful little "towers" may be constructed. Even in a jam-packed container it is always possible to add one more piece of broken glass. It almost seems as if the container never has to be emptied.
But if you only grab such an overfilled container you have to be aware that glass pieces will make "crack-crack-crack-crack" and the splinters will fly around with high speed. This risk is caused by sloppiness, because the container should already have been emptied whith one half of the current content.
The hero, who will take care about the problem has to ensure an excellent eye- and hand-protection. It is best to decant into a bigger container. Broom and hand brush should be at hand, because it is very sure, that after this action a lot of broken glass is spread on the floor.
