Scry is a verb that means to foretell the future using a crystal ball. 

Our word of the day is derived from the Old English word descrian (DESK ree ann) which had a broader meaning than today. In its early days, it referred to any act of divination. It later came to refer more specifically to acts of divination through a crystal ball. Here’s an example of scry in use:

When Kelly pulled out a giant crystal ball in her home, she caught my attention immediately. I thought she was going to scry the future, but it turned out she was just showing me a new lamp she’d just bought.
