My experiment with tumbling driveway gravel (which in kansas is primarily limestone) turned out interesting

I have no idea whats going on with the big piece. Its got all these weird bumpy bits that im sure are a harder type of rock but I have no idea what it is

Im not positive which side the only before picture of that rock i have is of....I think the first after picture is the same side...... it lost more mass than I thought it did tbh. But the fact that polished as well as it did is kinda surprising tbh. Probably won't ever tumble limestone again but its been fun to experiment with it cuz ive always wondered what would happen

Some of the little ones took on a polish and others didn't. Clearly they are different rocks but im not sure which is what.

#lucky ass Minnesota with their trans rights and agate filled gravel #tho finding out that a lot of gravel in Minnesota is filled with agates and jaspers has made me INCREDIBLY curious about #the composition of gravel in different places around the world #i mean im sure thats not difficult to figure out #its usually whatever is most common in the area #in kansas thats limestone #Minnesota has a lot of agates and jasper (lake superior agates are the state rock)#but it never occurred to me that different places would have different gravel compositions depending on what #rocks were most readily available #which i mean. it makes sense. you wouldnt be importing rocks for road or driveway gravel #youd just use whats around you #this world is full of interesting rocks to find
