Parabolas in the real world?

So I'm having trouble find real life parabolas for a math project. (not counting the St. Louis Arch)

It would also really help if the dimensions were included (ex:height, width, etc.)

Thanks!!!!Parabolas in the real world?
The path of a ball thrown up in the air with a horizontal component of velocity.
