My wife and I were sitting in a parking lot deciding what we wanted for dinner when I saw what I believe was a UFO

My wife and I were sitting in a parking lot discussing what were going to eat for dinner as the Ihop we were at just closed their doors. My attention was drawn to the sky as I saw a bright white light. I initially thought it was a "shooting star" until this half-diamond looking object ejected a fuschia, blue, and white stream of light. This object accelerated and disappeared in a matter of seconds leaving me screaming and my wife asking what was wrong.
