Here are some trial runs of the angle of repose lactose project. I did some trials with the lactose that is bigger in size and it had a hard time flowing out of the cylinder and didn’t form mounds as well. I also noticed that the fine powder lactose flows out better when it’s “fluffed.” The last picture shows the mound that formed from the fine powder lactose when it was compacted (i.e. tapped). The mound looks smaller because only about half the lactose came out and it came out in “chunks” (i.e. it didn’t flow out smoothly).
