Have you ever cleaned corn? If you haven't lived in a rural area, you may not. Cleaning is required to feed your livestock, especially chickens and pigs. They can't both eat stemmed corn, so you have to separate the individual kernels from the white stem part. There are multiple tools to do that and keep your bare hands from getting bloody calluses. Some of those tools look like toothed rings, which are placed on a corn stalk, twisted and moved to exfoliate dried calluses from the rod. This is what this free online game looks like: you push the ring at times when there are calluses on the bar, and you push it when there are none. In case of error, the round restarts.
