Craving sand

So I’ve heard of weird cravings and i know of Pica but i could never imagine until now how somebody could crave a non food item. I really want some damn sand or powder laundry detergent. I want to feel it dissolve in my mouth. Thinking about it literally has me drooling. Of course I’m not going to eat either but WTF!! I’ve been on a hunt for some pixie sticks but no luck, I bought a baby bottle pop to eat the powder, it was definitely satisfying but I want something grainier?? Any suggestions of something I could eat to satisfy the craving 😅
