Weird Fruit

So I went to a park near my school to try and film a video, but I ended up finding this amazing thing:



As I walked toward the tree, I though it was a tennis ball, which seemed random because there were no tennis courts near. When I got close enough, I kicked it around a bit, I didn't even want to touch it in fear of it being poisonous.

When I got home, I did a little research and found that it is a Osage-orange fruit :)
