like in older versions i think stone should break glass when it touches it but maybe a bit different. it should be that the farther it drops the more glass it breaks and different from the old way it shouldn't break it like air but like bomb creating a circle of broken glass so bigger if it falls farther. also if theres a way to make it more of a random shape then a circle that would be cool.

it would be very useful you could make glass vials that break releasing some element for a reaction.
