Cheetos baseball is only possible, so far as I know, with giant Cheetos. They are round-ish, cylindrical, really, and very hard and dense. They are actually edible too; at least in comparison to regular Cheetos.
I was at a party recently where I started pitching them to a young woman with a baseball bat. It was quickly discovered that this was fun. You can throw them and you can hit them. Try it.
Someone recently observed that it's sort of striking/maybe a little disturbing that this food is so structurally sound you can hit it with a bat several times. I didn't think about this at the time.
